Thanks Marc. Actually our rambunctious days are long gone (well...almost).
We're both pushing toward mid 50's. I think that's why we're finally making the big leap into trying a mainstream cruise. Although we definately enjoy RSVP cruises, we do want to be able to explore other destinations. Besides, the majority of our friends are straight couples so guess it will be no different than on land. The only thing I think we will really miss is being able to walk on deck holding hands and having an occasional dance. Yup...I know that sounds silly but we do really enjoy that. I do hope they still do have FOD meetings. Was reading that they no longer advertise them in the daily newsletter, but would be nice to meet others on the ship.
Enjoy your trip.
