This is our first trip to Universal Orlando with our 2 DDs, ages 13 and 16 when we go. (Though we've been to Universal Hollywood before.) We typically just go to WDW and stay in that bubble for a week. However, this time, we have 1 day available before we go on a cruise. The plan is to get 1-day/1-park Universal passes. We want to go to IOA, since this is where the Harry Potter world is. Please advise: 1. Is IOA where we want to go for 1 day? What I mean is, is there enough there to keep us busy the whole day for our DDs of those ages? (Yes, I really have no clue and am already feeling rather overwhelmed planning just the cruise and the WDW portions of the trip.) 2. What are the "must-do" restaurants, so we don't wander around aimlessly looking for food? Also, where should we avoid eating? Regarding restaurants, we are not picky eaters. Regarding rides, our DDs are adventurous and can take rollercoasters. The only thing is that my DH cannot take any rides that can affect his motion; he gets really nauseous. Thanks in advance for any help you can give us!!!!
