IMHO, a single, ambulatory straight male who books with a single cruise will be like a chicken in a den of foxes -- literally. Many of the people (women?) on these single cruises are looking to meet "someone". You may get latched onto and not be able to enjoy your "me time". It may be a bit overwhelming if you book with a single group. I have never done a single cruise but have been told that many of the activities are designed to match people up. If that is what you want -- go for it. But if you want some solo time and the ability to do as you please, I would pass on the singles groups.
I would suggest booking a 3 or 4 night Bahamas cruise. Those tend to have a younger crowd and are definite party ships (not drunken but party).
