We've done various times of the year, and August somehow "works" for us. For starters, baseball season (regular and all-stars) consumes our summer -- August is about the only month open!

With two boys in baseball and one dad as asst. coach on both teams, we are a wee bit tied up in the summer time! We will be at BCV on the 7th, then BWV from 8th-16th, then SSR through the 19th this year.
I agree about the school calendars -- most of your southern schools do start in early August. So if you want to avoid that crowd, look at mid to later August.
If you like water parks / pools, you're fairly well assured of enjoying them in August. About the only thing that would stop you would be monsoon-thunderstormy weather. It does happen, but we always try to make our trips long enough so that SURELY there will be some sunny days packed in there somewhere! (And a lot of hopin' and wishin' doesn't hurt either, I guess!) At least with August we know it will be WARM! We have had great Dec-Jan trips but also some REALLY cold ones -- way too cold for a swim. And we had a totally rainy Oct trip once -- so it just goes to show weather can be a factor WHENEVER you go.
I too am being a naughty little
DVC person <a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/347.gif' alt='Devil' border=0></a> hoping there are NO big WDW promos this summer. Word is, however, that there will be -- I guess one of the other threads was mentioning that Disney resrvation folks had been told to expect a fair amount of mandatory overtime during the first part of May... sounds like they expect their lines to be jammed with callers. The last summer package only extended to the July 4th week -- it certainly sounds plausible that Disney and/or DIsney Visa would make an offer for the second half of the summer too. And they are HEAVILY advertising all the theme parks on Disney Channels lately -- anyone else noticed that? Showcasing all the newest rides, etc. I've got visions of long lines already -- UGH.
Maybe I should sign in under an alias and post all sorts of messages on DIS and other boards about how AWFUL August is, how hot, crowded, miserable it is, and no amount of discount should EVER persuade you to go at that time!! And you fellow August travelers can post how much you AGREE! Just one hint -- get an alias or take your counter off before you respond or you'll blow our cover!! <a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/15_1_63.gif' alt='Peeking Over Fence' border=0></a>
