"Go to college" usually implies registering with a college and becoming a student, which, to justify, is going to require way more work than you'll ever encounter in a job. Perhaps you meant to say: "Take a vacation and befriend college-aged people who like to have fun while on it"?
In the UK we have "freshers week" where all the students party straight for 1 or 2 weeks.
That is the "most" fun part of college if you're into nightlife. Friends of students would come up in the 2nd year and have a lot more fun because they had been earning money by working a full time job while students were getting themselves into debt to have a "good" time.
I don't know, does everyone have such a good time in college? I had an okay time in college. I had a better time just going to travel without attending classes
You can always work after college. Going to college after entering the workforce becomes much harder (and you lose out on the social aspects if you're too old, or if you have to split time between work and school).
