When we were there last weekend for CVW they just told us August and that the dates should be set sometime in April. I know last year it was the first weekend, but seemed like the rumor mill was insisting the second weekend for this year while we were out there (not sure if there was any basis in fact to this!). Some folks there recommended making hotel reservations now for both weekends just in case and then cancelling, but obviously you can't do that with flights (unless you fly SW). I just don't think the date is set yet, or if it is, that they're letting anyone know officially!
