The usual order I suggest to coaster newbies so they can work their way up through all the coasters is: Mine Ride, Disaster Transport, Iron Dragon, Blue Streak, Gemini, Corkscrew, Magnum, Raptor, MF. You could throw Mantis, Wildcat, or Mean Streak somewhere in that order (but don't take a coaster newbie on Wildcat first, it's more intense than it looks!)
