If you're not planning to get there early, early to tailgate I'd suggest using one of the Park & Ride lots that should be advertised on I-95. DSis & her family have used the one at LPGA Blvd. area off of I-95. They park their car there as it's north of ISB & ride the bus down to the track. So far they haven't had any trouble in all the years they've used that. You might be able to go on the DIS website & see where the different locations are. Best bet whether coming from Orlando or Villages - watch the overhead signs that tell of the congestion, wait time to ISB/92. Just pack your patience.........LOL!!
Haven't had the pleasure of doing the FanZone - it was being built when my Dad retired from Nascar/DIS. Have taken the ride around rim road & also been in a car around the track at 100+MPH.
Most fun I'd had in a long time other than being inside when they were filming Days of Thunder!!
Enjoy the races everyone...........it's another one of those magical experiences. The first time those cars tear down the straightaway in front of you & the seats shake you'll wonder why it's taken you so long to be at DIS!!
