From what it sounds like the money is just to cover general expenses and dinners and stuff while you are there.
Also offering a nice safe backyard to camp in is worth something. I am sure that offer also includes use of the bathroom/shower. Camping in Florida 7 blocks from the beach and doing some good work would be a great fulfilling way to spend Spring Break. I would feel better putting $100 towards that then alcohol and bad choices. hahaha
that sounds like alot of fun, i would do it but for one i still hate planes and i don't know how much i would enjoy sleeping in a backyard with a bunch of random people. not that i don't like making new friends but i would rather spend spring break with my friends here. i don't like the idea of sleeping in a backyard in general.
