I like Leu Gardens. It's in a great location if you want to do a full local Orlando day. It's right by Loch Haven Park which has great museums and theaters like the Orlando Museum of Art, the Orlando Science Center, the Orlando Repertory Theatre and the Orlando Shakespeare Theater if you are looking for more entertainment or things to do. You're near downtown Orlando where there are lots of great restaurants (including Orlando's Little Saigon if you are looking for great Vietnamese food) and you're also really close to downtown Winter Park which is another great area with lots of shopping and restaurants. Winter Park also has scenic boat tours of their lakes if you want to check out some nature and some pretty cool looking houses.
