I can tell you that the last week of September/first week of October was absolutely PACKED last year, as a result of the free dining promotion....many families with school-aged children. Here's why:
1. Fall Break throughout much of the southern states. This year my older son is out from 9/29-10/16, and my younger son is out from 10/5-10/16. Many school systems have similar schedules in September & October.
2. Please forgive me for not knowing which holiday, but there is also a Jewish holiday that many schools in the country dismiss a few days for. I know we talked to several people last year that brought families at that time because the kids were missing school.
3. And finally, many people will change dates to save the money. period.
There will be people that can't or won't go at that time because of school, but please don't think the numbers won't change that much.
ADRs will be IMPOSSIBLE to get at the last minute, too.
