We went to Daytona USA in 2003 and found lots of interactive things to see and do, especially if Speedway is your "thing". Our 2 boys (then aged 10 & 13) really enjoyed a simulator in which they "drove" a vehicle which turned over during the ride! Another simulator let us all drive in a race against each other. There was a lot of speedway memorabilia, and the ticket also included a tram tour of the speedway circuit itself. We all enjoyed it, and thought it was good value, with enough to see/do for at least a half day visit, or longer if you spent more time looking at all the exhibits.
