Also a place, if we can, to meet in Orlando that may be of consideration could be Dave & Busters. All meet and go play some games together, plus they have a large cafeteria. They also have an Event planning link on their site.
Just saw this thread, Brothers Performance in deland is a nice place. I used to work @ Daytona and while its possible to get track time, its easier to do it through other organizations (SCCA for example)
