We will be going the 23rd-29th, too. Everyone should be back in school by then, so it should thin out families with school aged kids. My parents always took us in June. It was crowded, but we still had a blast. Even if it is crowded, we still get to eat for free, and hey, we will be at Disney, right? It's my first trip on my own w/o my parents. Dh and I are taking our dd3 and our ds1. At least summer vacation will be over.
