Well... I'm not the best person to comment on this one, but I have been in May and Spetember to WDW, and loved May, the weather was good, but not too hot, the crowds were fairly minimal. It was between Easter and Summer holidays. I dont think the pricing is too bad at this time of year is it Pam? The Epcot flower festival was on too.
I think another poll to find out whether we would have to meet during school holidays would be important, and see how many of our members are at school/college/uni etc.
