My wife, grandparents, and I will be headed to Orlando in March (15-22). We will spend a day or two at Disney but would like to know what else in/near Orlando may be fun to do (other than theme parks and preferally on the cheap side). Also, we plan to spend our last two days near orlando (half an hour out or less) if we can find a location of interest that close so we don't have far to go back to the airport on the last day, any thoughts?
