From the cadets we knew while living at West Point, their take is you have your ups and your downs, and for the most part, the ups outweigh the downs. Yea, some stuff sucks, but at the same time, cadets get opportunities that their classmates at a traditional university could only dream of. For example, one of the possible summer assignments is to go to Airbourne or Air Assault school. Where else are you going to be able to jump out or rappel out of helicopters? The camraderie you get between cadets is also unparalleled at a civilian institution. The motto "Cooperate and graduate" is something most cadets figure out pretty quick. The academics are great and offer a variety of majors; no TA's, professors with real life experience as Army officers who give a fresh perspective of what it means to actually lead soldiers.
Besides, you have to remember, cadets are still young adults. They definitly find ways to entertain themselves even if they aren't always in the most traditional ways.
For me, I want to go, besides wanting to serve my country and getting the best possible training before doing so, is that I want a challenge. I have friends in college who are doing well, getting their degrees, partying, but they really aren't being challenged and developing as much as they could as people. The cadets that I knew, they were the kind of person that I wanted to "grow up" to be. I'm glad I have that chance, and hopefully, I'll do them proud for their belief in me when I was younger.
