first and foremost, absolutely fuck cruises - absolute environmental disasters.
okay with that out of the way, I've been on one in high school and it was so great! Food available on demand, you aren't stuck in a car going from place to place with your parents bickering all the time, and activities are usually pre-planned at ports of call so if you don't want to organize it yourself you don't have to. there are plenty of nice things about a cruise that I will never again experience because of just how much damage they do to our oceans and atmosphere every single day.
