Thats good to know. I am going on Queen Victoria next year and was hoping that the sauna was still single-sex, just like Queen Elizabeth. Its quite true that single sex saunas are much friendlier places - I have had great chats with guys in there. When youre nude it just makes people more open to one another. On Queen Elizabeth quite a few of the stage performers use the sauna during the day - although the dancers are usually very toned so I slink away when they appear for fear of comparison.
I was on the Queen Victoria last year out of Southampton for 12 days. At first the sauna was not crowded, but by the end of the cruise it was standing room only. Some guys would come in wearing bathing trunks and see us naked guys there. They would leave and come back a minute later naked as well. I know what you mean about the entertainers in there. They are all well built and not afraid to show it. I just sit my pudgy butt down anyway!
