We are travelling in May w/ 3 kids. Staying at Port. We will have express ride access. I know 1fish & Ptreradon Flyers at IOA and Fievels at US aren't included. My question is do we go on & off whatever rides we feel like, or are we smarter to hit more popular rides first. We will be there on Sat at universal & Sun at IOS. With Express can we expect to do each park in 1 day visits? Thanks for expertise.
