Thank you but with me being a full time carer it's not going to be possible - I have stated that in my profile . maybe mention to members where you're going and when and see if you can connect with anyone etc good luck.
I don't think any of the cruise lines do meet ups of the sort your seeking, most ships are aimed at families anyway but that said good old British P & O cruises offer two adults only ships in their fleet, they are smaller ships .
Do check out the various signage people use to say they are up for some horizontal Olympics , for instance putting a pineapple logo on your cabin door, etc most cruise lines hold meet ups for singles and Lgbt etc , never been disappointed myself .
