Oh yeah we are HUGE rollercoaster people... that's the only reason we're going is for the intense thrill rides... otherwise we would just stay in Disney for another day. I have heard a lot of negative things about MM lately.. mainly that it is dumpy and lacks "atmosphere"... but really I am just looking forward to all those insane rides.
90 minutes? Thats better than what other people have been telling me... I have heard everything from "Leave 3 hours early!" to "Just spend the night near the park so you can first in line!" Maybe it's just me but really, I'm not the type of person that HAS to be the very first person in the park...
So thanks for telling me 90 minutes should be sufficient enough
