We've decided to take our trip the 2nd week of March - 2007. In 2004 we booked a pool home instead of a hotel and swore we'd never do a hotel again...lol. We LOVED the pool home. Anyway, we always have went in the summer months. Is pool heat needed in March? It's about $150 a week and I don't want to get it if its not necessary. I know that here in TN, March is still very cool but not sure about FL. Also, the kids are wanting to go to Blizzard Beach. Is it swimming weather? Any advice from those who have been in March? Thanks!
