There is a Roll Call for this cruise on the G&L forum at Cruise Critic. There is also a topic about cruisers in the DC/Baltimore area. You might want to check it out. There are at least two other gay couples.
Darin (GBM 41) and Carl (GWM 39) taking this trip together. Meeting up with other family at one of the bars (not sure which one yet) around 2:30pm or so for a meet & mingle prior to departure....
