We took DS to Disney in December of 2003. He was 9 months old at the time, but here's the few pieces of info I can pass along that were of great help to me!
-We requested a PnP from the resort, but did take our own sheet to help it feel (and smell) like home. Also-be sure that your little one is used to sleeping in the PnP! DS was so exhausted by the end of the day that it all worked out okay, but in hindsight, I wish I would have had him at least take naps in the PnP in the weeks leading up to our trip.
-We requested and received both a fridge and a microwave in our room. These were invaluable since DS was still on formula. I don't know about availability at the All Stars resorts, so you could always go with
www.abbf.com. We used them on our trip to rent a rocking chair, and were so glad we did!! I would use them again in a heart beat!!
-We took the Palmolive DishWipes to clean the bottles, but, as someone else suggested, we used the disposable cups with lids and spoons from First Years as well as the Bibsters.
-I read someplace the suggestion to pack "mini diaper bags" ahead of time. (i.e. a gallon bag with a diaper, a sample package of wipes (or a zip loc bag with some wipes), and a disposable changing pad.) It was really convenient to just grab one of those bags out of the diaper bag and be able to go. It was also nice that I could put the dirty diaper into the bag when I finished and just toss it. I did the same thing for meals: One gallon bag contained his baby food, bowl with lid, spoon, and Bibster, along with an empty bottle and formula.
-We also chose to bring bottled water from home to mix the formula for DS. I kept hearing comments about how the water at Disney tasted "funny", so I decided not to risk the fact that DS would think the same thing and refuse his formula.
-Although it sounds silly, I also took one extra garbage bag from home for each day we were there. You accumulate a lot of trash between diapers, formula packets, and food packaging, so it was nice to know it was all contained! I'm sure that Mousekeeping could provide this for you, but I was worried that we would miss him/her in our comings and goings.
-Another thread on this board touched on this, but it bears repeating: I absolutely loved the clear shoe organizer!!! We used it for all of our bathroom supplies, including the baby bath stuff, and all of our first aid supplies. Speaking of...
-I am a proclaimed overpacker (is ther an overpackers anonymous?! LOL!), and was insistent that we take baby Tylenol and Motrin, as well as a decongenstant and simenthicone drops. I was very glad we did! It's a long story, but the short version is that we used all of the items we brough, including the thermometer, and I will never travel without them again. Also-don't forget your insurance card, and the name and number of your pediatrician. The front desk at the hotel can provide you with the name and numbers of both the local hospitals as well as a service that will come to you at your resort. You never want to even think you'll need any that information, but you'll be glad to know it if the need arose.
-My DMiL, who traveled with us, was kind enough to buy "happys" for DS. We discovered that a few new toys were great for holding his attention during wait times. A trip to the Dollar store should yield you quite a few new toys that you won't feel bad if they get broken or lost without breaking the bank!
-Other items that we took: Anti-bacterial wipes for kids from Bath and Body Works and Clorox wipes for the room
-Items I wish I would have brought: small deflatable beach ball; glow sticks for at night and during dark rides; travel DVD player (if not for child, then for parent!); blank notebook, and washable marker and/or stickers for DS; notebook and pen for me to keep notes for trip report!
Hope this helps you to have an absolutely magical time!!
