My sister and her family are HUGE Harry Potter fans, so they adore Universal Islands of Adventure. I spent a day at each of the Universal parks with them back in November 2011, but hubby wasn't able to go because of work.
Sis and family are going back this April and invited us to come along. After a bunch of not sures/what ifs, they booked their trip, and after a little more of the same we decided what the heck, we'll go and give hubby a chance to see those other parks. He's never been to either one.
So we're going to Orlando, but won't visit any of the Disney major parks (which would be unbearable if we hadn't just been there last October). In addition to three days at the Universal parks with sis and family, we'll have two days just the two of us doing Downtown Disney, water parks, and Disney Quest on some old no-expiration tickets that have no more major park days but plenty of minor park visits. Of course we'll make some ADRs for non-park restaurants; where will depend on what's available just two months out.
Any other non-park Disney suggestions?
