Remember on typical cruise you will be lucky to have 1-2% solo/single cruisers. Also, crew is not allowed to fratranize with guests.Was sailing solo on Celebrity several yrs. ago with singles dining table in MDR,all women. Our waiter called up all the ladies except me, asking to come to their cabin for sex. He even put it this way. He gave me that look and I had given him a dirty look. He also knew me from previous cruises. Girls turned him in. Anyhow. next nite MaitreD comes by, says guy had to go home for a family emergency.They had put him off ship at that days port. He had been with Celebrity 9 yrs. One of their best waiters too. Vacations to Go,com does excellent singles cruises monthly, most lines too.
