I was there April 2003, and it was crowded, but certainly not unmanageable. It was spring break for our schools that week, but it varies so much state to state, and school to school, that you aren't likely to get EVERY school on spring break any week in that time period. However, I have to say, this opinion is from a woman who doesn't really get that frightened of Christmas crowds...I've been twice during Christmas week, and as long as you have a plan, and make ADRs, and go early in the day, you won't have too many issues. Spring vacation is SO much easier than Christmas! AND, you can use the pools more frequently...temps for us were in the 80's. Actually, my DH complained that it was too hot. Truth is, my DH complains about everything, all the time..........
