DEAR MISS MANNERS: Throughout our 54 years together, my husband and I have lived in, and traveled to, many countries, both for pleasure and business. Now, in our dotage, we enjoy cruising because it combines our love of traveling and boats.

When we happened to mention an upcoming cruise to some acquaintances, they unexpectedly purchased tickets for the same cruise. It happened to be a 10-week trip, and we spent the entire 10 weeks trying to dodge them.

We were not successful. They insisted that we dine together, and thus began 10 weeks of their special requests. For example, our waiter spent at least 30 minutes going over the dinner menu, describing exactly what each item was (e.g., sweetbreads) and whether it contained gluten, dairy, etc.

My husband and I have no dietary restrictions, but by the end of the trip, we were being served gluten-free and dairy-free foods just because of our dining companions. Worse, they ignored all the dress codes and were apt to use quite salty language.

Now, they want to cruise with us everywhere. They just found out about an upcoming cruise we are taking, and are actively pursuing tickets. How do we politely and firmly discourage this?

GENTLE READER: “My husband and I are looking forward to traveling alone this time. But we will be sure to let you know if we go on a group cruise in the future.” And then, Miss Manners suggests you keep a tight lid on your plans.
