In addition to the cereal bars, packages of crackers, individual crystal lite drink mixes, we also brought microwave popcorn packages that came in quite handy. We always go back to the room in the afternoon and head back out in the evening to see the fireworks. We would pop it and put into a large ziploc bag and carry in to the park to eat while we watched the fireworks. Also I brought a ziploc bag of some assorted candy that didn't melt (skittles, pop rocks, blow pops) - yes soo healthy NOT, but its vacation and last time the kids drove me crazy every time we went into the Disney Store or Marketplace they ended up wanting a $2 candy bar. Each day before leaving for the park they picked out one item to carry with them for treat after lunch or while watching an afternoon parade. I also found Disney Pez dispensers and bought a refill pack of Pez's--so one day this was their 'treat'. I know this isn't the most healthiest food to take with you, but it is vacation, and it allowed me to have some portion control on sweet stuff and didn't break the bank.
