One thing I will say to you is plan to get there at least 4 hours early. I've never been at the track on raceday, but I can assume that there will be at least 2 hours of traffic holdup on your way in (just to be safe I'd leave and get there as early as possable that morning.. it isn't like there's nothing to do there at the track anyways).
Honestly, we went to the 1st race in Kentucky this Summer, and it was a traffic nightmare, but that's because they didn't have roads accessable to 107,000 built yet. I'm sure Daytona or any other track will be
alot better (we sat in traffic for 5 hours and missed the start of the race by 31 laps). But where we sat (it was a sell out crowd) we didn't have any yelling, idiotic rednecks anywhere beleive it or not. After the race in the parkinglot there were alot of drunks, and anger at the traffic (yes it was just as bad leaving) but generally, there was alot of people who really weren't the deep "redneck" steriotype. Of course as an American, I'm sure my view on what a redneck is exactly is different too, but the people never gave me any problems.
Seats towards turn 1 are very good, you'll get the full experiance of the velocity and energy which the cars are carrying
As always, it'll be exciting I'm sure
