we'll be spending a lot of time doing kid stuff in the parks but would like to get to some adult rides w/ my mom watching the kids. we'd like to do Spiderman, JP River Adventure, Popeye, Ripsaw, & Poseidon's Fury at IOA. Mummy & MIB at USF. can any of these attractions be done in the p.m. while the kids rest in their strollers or are there some that really should be done in the a.m. to avoid lines? we can also try the express system if needed but i wanted to get a feel for which rides out of the ones i listed are the most popular. i'm thinking Spiderman, River Adventure, Mummy & MIB have to be done in the a.m. Is this correct? we're going in mid-may, thurs. to ioa & fri. to usf. thanks.
