Universal in June?

[dizneefreak29]

I am taking my younger brother on a Disney Cruise for his 17th birthday in the middle of June. The day we get back, we have a 6:00 p.m. flight and he REALLY wants to spend the day at Universal. Any experts think we can actually do this? We went to Universal for a weekend in October and he loves it! I'm not sure how crowded it will be during June.

Thanks in advance!
