We were there the second wek of June last year. Regarding the weather, we found it to be <a href='http://www.smileycentral.com/?partner=ZSzeb008' target='_blank'><img src='http://smileys.smileycentral.com/cat/28/28_1_9.gif' border=0></a>. In fact, hotter than we expected even though we are from NC where summers are hot and humid. The key for us was to take breaks in the middle of the day, mostly to swim. We stayed at AS Music. It usually meant a 3-4 hour respite from the parks in the middle of the day, but it was really essential. The crowds were not too outrageous, but should have been smaller considering that MK closed at 7pm for a couple of nights -errr, afternoons -we were there. In fact, my only complaint was that the heat could have been a bit easier to handle in the MK hours were a teensy bit longer.
