We went last year in April and May. Both were hot. You will find that the day before Memorial Day and the day of will probably be busy but not as busy the rest of the week. Keep in mind that the Southern schools are out of school by then, and that's why we went.
Also, bear in mind that the weekend after Memorial Day - first weekend of June is Gay and Lesbian weekend. We were checking out the day that started and even received a memo under our door about it and the events planned.
If you have anymore questions, please email me privately.
Thanks - Diane
