We have been both in March and May. In March both times were spring breaks and one was the week before Easter. We love going in March. The weather is great. I wore jeans but everyone else wore shorts. All were comfortable. May is nice too, just a lot warmer, but not too bad. We have always stayed at the WL and love it. Next time though we want to stay somewhere else just to be different though. I think you will enjoy it whenever. We have never experience a huge crowd at any of these times either.
