Do yourself a favor,and get in touch with a cruise travel agency. Years ago, there used to be many more single cruises, available, so having a professional to give you all the appropriate info, will be well worth it. Perhaps there are specific cruises geared for a younger demographic. Reemember if not, there might be a significant number of older passengers in the group.
Good luck,and, come back and let us know how you made out.
Trip, with her book & tea!
