A bunch of my friends and I are graduating high school this year, and want to go on a cruise as like a sign off.

Most of us will be 18, but two of us will only be 17. Are they allowed to go by themselves? If not is it possible that an 18 year old friend can count as a guardian? Or do we need someone who is 21?

Thanks a lot guys.

Try going to the cruisline's website to find out. It'd probably be in the FAQ section. I've been on two cruises and the BEST vacation you can have (especially if you're 17-18). You're gonna have an awesome time.
