Most of the posts in this thread are spot on. Everything, and I mean everything is provided for you. Just bring a comfortable pair of shoes. You'll eat like a king too so be careful, a few people commented that they gained some weight.
Just keep in mind that transportation will not be provided to Roswell Friday night. So if you are trying to catch a late flight out of there, consider having your own rental car for the week so you can get back there. There were a couple students who desperately tried to get to Roswell in time to take a flight and there was only one Lyft in town and they didn't get off of work in time and the other option was to call a taxi from Roswell which will cost more then the cost of a weekly rental car rental. Expect to be done with class/graduation by 1630.
