jaygatz, I'm pretty sure they had hopper tickets because they did discuss going to Blizzard Beach but decided not to as it wasn't warm enough. The YES activities were scheduled in the mornings and they had the afternoons & evenings free.
I think it would be a great idea for impoverished kids to get a chance to go to WDW. I know that my daughter's school had several fundraisers (Little Caesar's pizza, poinsettias, popcorn) that the kids could participate in if they wished. They also gave them ideas to earn money in other ways (babysitting, collecting pop cans, etc). Some families paid for the entire trip using these methods. I hate messing around with fundraisers too much, so I told my daughter I'd pay for the trip, but she had to raise her spending money. She did some of the fundraisers, babysat, saved birthday & Christmas money and had about $350 for snacks & souvenirs.
