My tips with kids are:
#1 - Pipecleaners from the Dollar Store. Keeps the kids entertained in the car, in restaurants, in line, etc. Pull out a few and see what they can make.
#2 - Glow sticks or glow necklaces (the three pack of skinny ones with joiners) from the dollar store. They love them when waiting for Illuminations, fireworks, or Fantasmic and it saves you from the temptation of buying expensive Disney light up things.
#3 - Ziploc's - can't say enough about them. Carry a few extra in your backpack for those emergencies. I also pack the kids clothes in them. You can purchase the 21/2 gallon big ones - but sometimes you have to really look for them. One outfit (short/shirt/underwear/socks) per bag and then put the dirties back in the same bag. In the morning I just hand the bag to the kids and they dress themselves.
#4 - your own bendable plastic straws if you plan to go to AK. They don't provide them so as not to hurt any animals, and they do fill the drinks up to the top! Just put a few in a ziploc, and make sure you take them back with you when you are done eating.
#4b - Just thought of this - at AK make sure you purchase the AK Meal+ deal. It is a tremendous deal. Just look at the menu board and it will explain. You get meal and drink, plus coupons for ice cream/popcorn and another coupon for a bottled drink to use later in the day for $5.99.
#5 - Bring your own misting fan (Squeeze-breeze) in case it is hot. We have 3 from
Walmart at home ($4.99) and didn't bring them at the beginning of October, so we had to buy a Disney one ($17.!!)
#6 - Quarters and pennies for pressed penny machines in a mini M&M's tube. Each pressed penny is .50 + 1 penny. It is a nice inexpensive souvenier DD8 loves collecting them. If you are going to do this, make sure you purchase a pressed penny book the first time. They are located either at the cash register or on top of the pressed penny machines. Press the penny, then immediately put in the book. The kids love admiring them!
#7 - plan a general itinerary, and book your PS's. Decide ahead of time where you think you might want to eat, and book the PS's. You can always cancel, but with a party your size and hungry kids, I'm sure they won't want to wait to eat.
What I do is take a clean sheet of paper, draw columns for each day, plug in where we might eat for meals, any sit down restaurants, then work in special events (Illuminations, Fantasmic, Parades) and what park(s) we will visit that day. Believe me, it is a real time saver!
