Deb, while I don't know of any other singles going on this cruise, I do have a suggestion (in addition to reading all my articles in the singles section of Cruisemates). After Mum goes to bed, go out on your own and find out where the party animals are! Usually, they are in the Discos, which, as a rule, stay open long after the other clubs and lounges have closed. I remember cruising on RCI's "Sun Viking" many years ago. They gave away souvenir "Night Owl" pins for those still in the Disco at 3 a.m. closing. I am proud to say I brought home seven of those pins. Of course, I was younger then and don't think I could keep up the pace now. :-))
I also always advise single cruisers to find out when/if a get-acquainted party is scheduled. If there isn't one, seek out the cruise director and ask him/her to arrange one and volunteer to help.
Just make this your motto: "To have fun cruising single, you've gotta get out of the cabin and mingle!"
