SAM is great. It's the anti-COT. Your days end at 14:30. You have no homework, no assignments, no tests, and no uniform inspections. We never came to attention whenever colonels walked in the room. The weekend is free. Attending SeaWorld is free with your military ID. And you get full 45 days of pay. To top it all off, you'll be reimbursed for travel and lodging. I walked away with thousands of dollars last year.
Now the bad: my class didn't get to fly. The lectures are kind of lame. The tours of museums are a drag. On a whole, you waste two weeks of your precious summer to wear a uniform.
