Not sure how old you are, but a lot of adults love to do a monorail bar crawl. Also, give Disney Springs a visit! You can get lots of shopping done and I heard Homecoming is an amazing restaurant if you can get reservations for it. Personally, I don't have a lot of time outside the parks, but just exploring the different resorts is fun. I went to Port Orleans on the last day of my trip and my group rented out a surrey bike, and it was so much fun!
