Unfortunately we were limited on when we could take our trip to Disneyland, so our dates are pretty firm. I see that during the time we are there (first week in June) there are a few Grad nights and I've some threads about people wanting to avoid them. We are normally Disney World visitors, so what should I expect about going to the parks on Grad night? I know it is a ticketed event and it sounds similar to one of the after hour parties, but what should I expect during the day, just increase attendance or is there other problems?
