This is a great point..I think MoM will fill this voidIt'd be nice for the Potter attraction to be two things:
1) A family ride
2) Not a coaster
In other words, a dark ride. Potter attractions (sans HE which is more transportation to me) are all either coasters or thrill rides, but we don't have an innovative family experience that's much different. MoM, if it can hit that demo, it's got everything it needs for the Potter package to be complete.
Perhaps Universal is under the assumption that the core demo for Potter fans are at an age that they love thrills :shrug:
Its been said a million times, but I'll say it again. Gimme a boat ride at Universal.
A boat ride would be nice...Potter would be perfect....Although after this and MoM I would hope no more Potter...They are using it as a bit of a crutch
