I've been on several cruises and hate paying the single supplement. I don't smoke or drink, although I am basically a night person (don't go to sleep till around 1 or 2 am). I am able to travel without much notice so for a good fare and decent company I could take a "last minute" cruise. Three to five day cruises are best for me. Theme cruises are okay if they are about history, music or art. I don't mind dressing nice but dislike dressing formally. I'm about a half century in age and rather mellow. Oh, and I'm straight!
