Heres the deal, me and my boyfriend are looking to go on a cruise. Only problem is we are both under 21. I know a lot of cruise lines require someone over 21 to stay in each cabin. What I want to know is which cruise lines would we be able to attend, basically, which cruise lines allow 18+ to be aloud in cabins by themselves. I am also wondering which cruise lines allow 18+ year olds to drink on board. Thanks for any help!
