We are a family with an 8 y.o. girl, 12 y.o. boy and a 16 y.o girl. We plan to spend 1 full day in Universal Studios Orlando. They ALL enjoy fast roller-coasters and extreme rides and we would like to do as much of universal studios as we can in one day. Should we spend the whole day Universal Studios or should we go to Universal Island of Adventure as well,.... or what should we do? Am I crazy thinking we can do everything in 1 day and still not be too rushed. Please help! Thanx!
