A meal at the Disney park is about $10 per meal, per person, drink included.
Unless you go to a fancier restaurant in the park , It is not necessary to tip at the parks.
Epcot and Magic Kingdom have the most to DO, ride wise. You_ll probably spend the WHOLE day at them. Hollywood Studios, my friend and I went through in like 3 hours, and we were bored. There is the tower of terror and rockin roller coaster and the toy story ride. Those are the most fun. Animal Kingdom is fun, but in the summer its HOT. The animals tend to get out of the sun, and they usually only come out in the morning, so get there early if you want to see them.
You might also look into packing sandwiches to take into the park to save you some major bucks. They allow backpacks, but they also have to be checked. So you might want to pack some water bottles to save you a good $3-4.
I would also stay at a Disney Resort, because Parking is $12 per day. And if you stay at a Disney Resort they shuttle you to the park or to the monorail station. Or you take a Disney Bus from Downtown Disney (free parking) to the Contemporary Resort for Magic Kingdom or Epcot... Monorail hopping :)
Pop Century resort is cheaper than most of the hotels in the area, and it is a Disney hotel, so they allow you to get on the bus and take you where you want to go.
Everything is very overpriced. So bring more than you think you will actually spend, plus if you have a visa, they have places to get money out at.
Hope this helps.
