We've gone in April the last two years, and I really thought it wouldn't be a problem, kids show up ang go to grad nights no big deal. However in my opinion the amount of teenagers there earlier in the week was much higher and created a much busier WDW than I use to have at the same time with no grad night.Also I saw what I consider to be to many teens just out by themselves causing problems and being rude.My wife's a High school teacher and with her school the students have to plan ahead of time where they are going, and they have to go together with the chaperones. But this didn't seem to be the case with most other schools.
