The Daytona 500 is the 19th which is the day before President's Day, so it is more crowded because of both. We went to both races the weekend of the 500 and then spent the rest of the week in WDW. It was more crowded at the beginning of the week and got much better by wednesday and thursday. We did see a lot of people walking around with shirts from the race, and we talked to a lot of people who turned going to the race into a WDW vacation, so the crowds will be up.
