We've never been President's Day, but have done Columbus Day 4 times in the last 6 years. Trust me when I say that last year's Columbus Day was twice as busy as it was a few years ago.
With the food & Wine, Halloween parties, good weather, etc., October is much, much, busier than it used to be. And, now many schools in states like Indiana, Kentucky, and Tennessee have fall breaks. Within a few more years, October will be as busy as Spring Break.
