We did years ago when my kids were little. We only did a day trip (although we went again before we left). I always made sure we had rest days on our weeklong trips. We drove over to Daytona on one of those days, the kids played on the beach, played in the ocean and then we ate dinner there. We weren't expecting to pass the Daytona 500 Speedway, so it was a nice surprise when we did. We didn't want to give up our beach day to tour it, so the day we were set to drive home, we made a detour and drove over to tour the speedway and then left for home from there. If you have the extra time, I would do it.
