Were going for 14 days in Feb. Don't know of anything yet. But I have gone early February and early March in the past-- and there are always cheerleading, dance, ect competitions at both times. However, I've never noticed an issue with this.
Remember President's Day week is becoming more and more crowded each year. Unfortunately that is one of my 2 weeks we'll be there. I prefer lower crowds (even if it means early hours). However, DS is off school and we can finally stay 2 weeks w/o him missing 2 weeks.
