The "Merry Widows" program no longer exists in it's previous form, for a couple of reasons, but primarily due to the changes in the design of many of the ships. At one time, ballroom type dancing was very popular and the Merry Widows cruises offered "dance hosts" who would join the group. This provided an opportunity for the ladies to dance each evening with a semi-professional ballroom dancer. (They even had dance cards!) But the ships no longer cater to this type of dancing which requires a fairly sizeable dance floor. Though this wonderful music is offered onboard, it's generally not in one of larger lounges (these now cater to the younger crowd.)
That said, there are still plenty of opportunities for you to travel with groups of other like-minded women. I suggest you give our travel folks a call and let them know what you're interested in. There's a ton of great cruises available for all types of interests and destination. You can reach them at 1-877-530-4368. Happy travels! Sandy
