We're planning to go to DW and hopefully a Disney cruise in 2016 for my 40th birthday. I'm a teacher and the best time would be summer or Winter Break. I hate extreme weather (especially humidity) but I'm hearing it's crazy busy during the holiday season. If we were to go in mid-June would the weather be bearable enough in order to avoid holiday crowds? Our kids will be 5 and 7 by that time. Basically, which is the lesser of the two evils?
