I have been on 10 Atlantis cruises. I have enjoyed them all, some more than others. The cruises that go to Mexico and the Caribbean are more party cruises and have younger crowds...kind of a big circuit party most of the time. Other cruises to the Med, Baltic, Asia, etc. are older crowds because they cost a little more and are more focused on interesting ports'o'call. Before I ever went on one i had the feeling it would be a lot of unfriendly people with bitchy attitudes. I have never found that to be true at all,..everyone is super friendly There are always people of all age groups and there is always a ratio of single and partnered passengers. More singles on the "party cruises." The accomodations are always great, the entertainment is excellent, and there are so many things to do that if you try to do too much by about the third day you think you're going to die...lol! If you have any more questions please send me an email.
