Hello Cruise Vets!! I've never cruised myself. My fiance is going on a cruise with her best friend May 6th Mariner of the seas. She is pretty active where as her friend is pretty laid back. I was wondering is it safe for them to do a few day activities alone (she's already told me she theyll stick together at night) should you always do all activities in pairs on these ships. You hear the stories about people disappearing on some of these ships is why I'm concerned. My second question is are there lots of singles guys on these ships hitting on women?
