We were there March 7-13 last year. The parks weren't too bad at all. From what we were told, the "true" spring break starts the following week- I don't know how accurate that is. As far as weather, the first day we were there it was yucky. Cold, about 55, and rainy. The next six days- each was better than the day before. It his 80-82 four of the six. The last day was a little cooler- around 65 and a bit windy, but in the sun it was still nice. I think you'll have a great time.
