Unfortunately, the only time that I can travel to WDW with my family is July...ugh! I have a 2 year old and 5 year old. We plan to stay 10 days so that we have ample time to relax. Do you think it's feasible to experience WDW in July??? Thanks for ALL your help and input! 
Be prepared for it to be HOT and be sure to bring rain gear (ponchos and stroller cover) since it often rains in the afternoon in the summer (usually not for long, but you don't want a soaking wet stroller!). Drink lots and take advantage of airconditioned attractions when you need a break. We don't usually do afternoon breaks, but I'm sure a dip in the pool is a great way to cool off in the afternoon too.
