I agree with coach on this with one caveat... all the races at DL and now 2 of them at WDW (ToT on Columbus day and W&D on Veterans day) are being held on "holiday" weekends. I wonder if WDW would be pushing the race to the Sunday before Presidents day weekend next year- rather than the Sunday after. Seems they like to tie the races when possible to a 3 day weekend.
Logistically, it's crazy busy that week because the East coast has a winter break that week- so it's always uber crowded. But they can charge more for hotel rooms if they do that... soooo... who knows?
I'm hoping they don't and go with the Feb 23 date. Crowd wise, it's busy the first couple of days, but empties out by Sunday afternoon. So it's a great after race vacation!
