John G - I am also on the CFL Alaska cruise -my first one with a singles group (I am going with a friend, who I have travelled with, so no cabin-mate surprises). I have done 2 other Carbbean cruises with a group I belong to (~300 go on a cruise over New Years Week) and I will be going with that group this year as well on Navigator of the Seas Eastern Caribbean.
With a group at least there are people to eat with and hang with, I also have done excursions myself but always manage to meet people. I can also be alone when I want, too! No rules you have to do everything with a group -
I am thinking about Europe or Scandinavia/Baltic cruise for summer/fall 2006, so I am keeping my eyes open for group/singles cruises. Still too early, but I can start to dream.
