Just went last month. May 13-19. It was awesome! Great weather - mid 80's during the day, cooled off into the 70's in the evenings. Never waited more than 15 minute for anything!! Space Mtn. wait time said 20 minutes, got inside and it was less than 5! We arrived on Mother's Day, but didn't go to a park that day, went to DTD instead. So don't know about the crowds at the parks that day, but the rest of the week was great!!
