Disney World Conference?

Some tips. Take an afternoon break at the hotel swimming pool or just a nap in the room. It's so hot and humid. Take a money belt for cash and credit card. Just carry camera, sunscreen, sungles etc in tote bag big enough to include souvenirs, but don't buy any until you're on the way out so you don't have to carry around all day. In the summer you may need a rain poncho. The ones they have for sale in the parks are cool. Your daughter will want to go to the Magic Kingdom every day. Don't try to see every thing, it'll never happen and all you'll do is get stressed out and snap at each other and daughter will be whining. Take your time and see what you can. Be there in the morning when the park opens and go to the more popular rides first. The lines can be up to 2 hours long.
