Address book and stamps, so you can send out postcards to friends and family at home. Another idea --
Aloe - our family found it extremely useful (we used almost all of a 20 oz. bottle!) in the summer heat. (Jennifer N. Labuz)
Antacids
Anti-bacterial lotion - This was a must before all meals when we couldn't get to water. (Dawn, Ed & Eric Pauli)
Aspirin!
Pack an Autograph book and a fat pen (so the characters can hold it).
Backpack - to store cameras, ponchos, etc. in.
Baby Powder
Band-Aids
Bathing suit
Batteries - for still and video cameras Battery operated personal fan -
Beach Towels - For the water parks. Disney resorts provide towels for the pools. (Tracy)
Beach Shoes - those rubber-soled stretchy neon shoes, for walking to the pool, or at one of the water parks, no need to go barefoot and stub your toes.
Bottled Water - if you're driving and can throw a case in the car it makes it that much easier to grab some water on your way out each day. You'll NEED the water in the warmer/hotter months!
Bottle of wine and the opener!
Disposable Camera - especially the Underwater type if you plan to go to the Water Parks
Cell phone with battery and charger base (Bob & Marjie Gold)
Clothespins - for hanging wet swimsuits in the shower as well as closing up bags of snacks. Our hotel (a moderate one) had a clothesline in the shower. (Bcmagargee)
Contact lenses - make sure you bring *both* a spare set and your glasses.
Cooler - a soft, collapsible one to tote sandwiches and drinks to the water parks (PTKeil)
Dental floss
Ear Plugs - My daughter (age 5) is very sensitive to loud noises. In certain attractions, we found earplugs to be a great help for her She carried them in her fanny pack and we just popped them in as needed. (Christine)
Empty small suitcase/duffle bag - That way, when I load up on t-shirts and goodies, I have something to carry them home in! (buckylarue)
Fanny pack for you and the kids.
Film - Higher speed (over 400 for inside shots), Polaroid film - WDW does not sell it on property (Nikki) and extra rolls!
Small Flashlight - for reading maps or guide books in dark waits
Johnson and Johnson Foot Bath - Those little orange and white envelopes.
Golf glove and golf shoes
Gum - If you like to chew it, buy it in advance; you won't find any for sale on Disney property
Hangers - for pants and shirts (Deb suggests if you stay at a Disney hotel, ask housekeeping to bring extra to your room)
Hats - straw, baseball whatever...something to bounce the sun off!
Insect repellant
Jacket for dinner at Victoria and Albert's at the Grand Floridian (they can provide one)
Frozen Juice Drinks - We found that the Capri Sun juice drinks (in the little pouches) were the perfect size and just sturdy enough to haul around in the back pack. Also, (if possible) freezing bottled water the night before heading out (assuming your room has a little fridge that can be turned up to extra cold), makes them extra refreshing just as you decide you need a cold drink. (D. Basham)
Kleenex
Laundry Detergent - Rather than paying high prices for a small box of laundry detergent, bring some from home in a resealable plastic bag. Doing laundry during your trip also allows you to pack less clothing. (Jennifer Watson)
Lip Stuff - like Blistex or Chapstick - with sunscreen!
Local Access Number - for ISP to check the e-mail!
Permanent Markers
Pocket Binoculars (David Miles)
Prescription Medicines - I suggest that you pack at least 3 extra day's worth of any prescriptions for everyone in your party, and make sure they are in the carry-on luggage, just in case anything happens that you do not leave on schedule. It can be a real hassle getting prescriptions filled long-distance, and might take a day or two to get hold of your Doctor to approve them. (buckylarue)
Moleskin for your blisters
Nail clippers and file
Needle and thread
Night Lights - 2 pack of inexpensive night lights. No bumps and crashes in the night if you just stick these in the outlets. The kids will feel more secure if they know they'll be able to get to the bathroom quickly and easily, and you don't feel bad if you leave them behind (which I usually seem to do!) (John)
Notebook or pad and pens - especially if you're going to write a trip report
Q-tips
Pager -- If you have nationwide service (or can get it inexpensively for the duration of your visit), your pager can help you keep in touch with your family at the parks. (Jennifer Watson)
Plastic glasses for poolside
Plastic silverware - especially spoons (for eating in room)
Portable CD player and CDs -- Familiar music can help you get to sleep at night in an unfamiliar hotel room, or can just set the mood for fun, romance or relaxation. Having a CD player on hand lets you try out the cool CDs you can pick up at Walt Disney World, too! (Jennifer Watson)
Proof of Insurance - to show when you rent your car so you don't need that expensive CDW (collision damage waver)
Rain Poncho - so you can find your group amidst all those yellow slickers!
Safety pins and/or Diaper Pins - for broken zippers or missing buttons
Soap -- Bring a small bar of your favorite bath/face soap, stored in a plastic bag. If you have sensitive skin, don't assume that the soap the hotels provide will work for you. Some of the moderate hotels don't provide bar soap in the bath, either. (Jennifer Watson)
Sensible shoes -- Comfy, well-broken in shoes are essential. This isn't the time to try a new pair of shoes. If you must get new shoes for your trip, be sure to break them in well before you depart for Florida. (Jennifer Watson)
Extra Socks and Sneakers and Undies - One thing my daughter and I found when we visited in August, was that we ran out of clean dry clothes pretty fast.
Stain Stick - the laundry pre-treating stick. Since none of us like to do laundry on vacation, just rubbing the stain with the pre-treatment will let you hold off doing laundry till you return home.
Sweatbands - if you use them, bring them - very expensive at the parks.
Swimming goggles - as sometimes the chlorine from the hotel pools can be pretty high. Of all the things our kids enjoyed the most, was the hotel pool.
Hard covered Suitcase - My wife and I found that an old hard side suitcase filled with snacks and breakfast foods as well as drink boxes made having snacks and breakfast (get a fridge in your room for milk etc.) a big money saver. When you return home you can also use it for all those souvenirs you purchased and can't find room for. (Charles Toles)
Sunscreen
Sunglasses - for ALL members of your traveling tribe, and don't forget those handy-dandy straps that keep the sunglasses hanging around your neck. Much more convenient than tucking the sunglasses in a pocket or fanny pack every time you enter an attraction.
Tape - I always bring a small roll of receiving tape. It has repaired my suitcase when I arrived in Moscow with a big whole in my suitcase with stuff falling out, it has repaired flip-flops that flipped to pieces on my way to the pool, it has repaired book bindings and stuck notes on doors for me and well, you get the picture. It's a great temporary relief when you need it.
Toaster - Take a toaster and food for breakfast, snacks, and various other bites when you are at your room. (The Percey's)
Tickets (or reservation numbers) - Confirm or obtain airline seat numbers & departure times the day before. We got to the airport over an hour early and still got 3 middle seats for ourselves! Since we made our plans 3 mos. early, we also found the departure time had changed by 20 minutes. Nothing the airline called us about, but 20 extra minutes in an airport with kids is not part of a well-planned vacation. (Nick)
Tote Bag - to store ponchos and other items in. Another reader writes: and we'd recommend waterproof tote bags and/or backpacks for keeping cameras, etc. out of the rain.
Toys - for the kids (Tracy)
Trash Bags - a) helps with keeping room clean, trash cans full up easily and b) dirty clothes- room stays a lot more organized. Every morning I would grab a trash bag and throw our dirty clothes into it, no risk of losing any articles.
Tweezers
Two Way Communications Devices - are invaluable at the parks. I'd say we get at more done in a day with them because there's never any waiting, you can communicate/change plans on the fly, split up and regroup effortlessly.
Combo TV/VCR for movies during the ride down and in the hotel room.
Umbrella
Video Tapes - extras!
Watch
Water Bottles - especially in the summer. The bottles with the belt clip to be most convenient, no need to carry the bottle in your hands, an empty one or two also.
Water shoes - to wear to/from as well as IN pools/water parks.
Wipes - we found, having 2 young children who are out of diapers, it is still imperative to carry wipes of some sort. They get very sticky from all the junk they eat while in the parks.
Ziploc Bags - I always find a use for these. I fill my refillable mug on the way out each day; wash it out when I'm done and put it in the Ziploc bag till I'm back at the hotel. I can then refill it on the way to my room. Another good use is to keep film together. Ziploc bags are also useful to keep things dry at water parks and in the rain. Great for cameras, spare clothes or soiled clothes if you have little ones. You also don' t have to worry about finding a waterproof backpack.
