A roller coaster camp is where you spend the night or more than one night at a park and overnight you do fun things like ride rides, have a scavenger hunt etc... I can only think of one place that does it, Kings Island. They tried it out last year and I think that they may do it again. Not 100% sure on that though. Sounds like a lot of fun to me!
