Heading to Orlando with a couple friends (all in our mid-late 30s but young at heart) next week for a long weekend getaway with no definitive plans and the flexibility to day trip within central Florida. What are some fun things to do in the region that aren't part of the "Big 3" (Disney, Universal, SWE)? Not saying they're off the table, just looking for some things that are a little more laid back, off the wall, and/or different from the major parks.
