We are a family of five: parents and kids aged 20, 17 and 15 - its our 3rd trip to Orlando as a family. Kids have been without us there too. We have two half days and two full days during March break and want to be sure we are using them as best we can. We thought we'd visit Islands of Adventure for Harry Potter, Magic Kingdom, Epcot and MGM. Do you think we can fit it all in? Which ones are best for the half days (one half day will be 2 PM and on; the other half day is morning until about 1 PM) Thank you for any advice.
