We're looking at either May 2013 or September 2012 for a week trip to TCI. We're willing to take the kids out of school for 3 days max - so we're debating between 9/15 -9/22/12 (kids have 2 days off for a Jewish holiday) or 5/22 -5/29/13 (which is Wed to Wed and has Memorial Day in it). Which time would be the best weather? Anything else we should keep in mind while making these reservations? Thank you.
