We are adults in our 50's with our adult daughter, coming to Orlando for 5 days, beginning the Thursday before Memorial Day. We have been to WDW and Universal in 1990. We went to Epcot 2 days, Magic Kingdom 1 day and Universal 1 day. I assume a lot has changed in the last 23 years. I am interested in going to the Harry Potter experience and adventure Island at Universal. Would 1 day would be enough there or would we need a 2 day pass? I was wondering if Epcot was still the same, as I enjoyed it before. Is there anything new there? Is there anything else in WDW I should see? Hollywood studios? Animal Kingdom? Would I need 2 days in WDW too?
