I went to Disney in August of 2013 it was awesome.
Too hot then, for me.
We've done once in October and this will be twice in April. Weather good both times so far, and the forecast for next week is looking pretty good.
Agreed. Disney has done a good job in promoting "off dates" so there are fewer really light days left, but September, October, November (except Thanksgiving week), first two weeks in Dec., latter half of January and Feb (minus Presidents week), April (except for Easter week) and even early May. are reasonable for temps. and crowds. Jan/Feb the most iffy for temperatures (at least on the revised Dean scale)
