Ok, I live here and this past May was a rare and I state again, RARE May with lower humidity and milder temps. Usually May is hot enough that I have my central air on already. (any other FL people care to agree with me?) This past May was lovely. Depending where you are coming from, it may seem hotter to you than you are expecting based on the posts I just read. I live about an hour and a half due west of WDW and while May is really summer here, there is generally a large difference in the beginning of May to the end of May. Beginning of May the humidity is lower but it can be humid. End of May it's summer. Crowds are ok. Not summer time but not spring break either. I just don't want you to expect lovely "spring" weather here anytime in May. It's a transitional month yes with lower humidity but it's still hot.
