I think it's a solid package too. In total, including the two Sky Fly's, the Dual-loading coaster, the Mack Interactive Boat system, the flight theater, and the show; it's a diverse package that should have things that vary for all sizes.
Could there of been 1 or 2 more flats for smaller sizes? Probably. But I do think the play area will also help fill the void. And compared to any of the other area's so-far, this one's trying to balance itself out as a mixture of everything.
