A Cunard cruise is on our short list of things to do in the very near future. In fact, since we love cruising for the sake of cruising and are not really interested in visiting a lots of ports of call...many of which we've already visited....a Cunard trans-Atlantic cruise is right up our alley.
As to table size, we've done everything from a table for two all the way to a table for twelve.
Bottom-line, I think we prefer larger tables. We're both outgoing and can find interesting things to both talk about and learn from a diverse group of people. We're used to dining as a pair and have no problem with that but like the camaraderie of a large group.
But as this thread indicates, each to his/her own.

Having sailed recently on the QM, I think the assumption that the other diners would be over 60 is wrong, especially in the Britannia Restaurant. The 'older' set is more likely to be found in the Grill restaurants. I know, I was one of them at 60. But then, this is the crowd with whom I have much more in common. And a table for 2 has neighbors and one can always chat with them if the spouse gets boring or sleepy.

That's another reason I won't cruise. Cruise ship companies have this insane idea that everybody wants to eat at tables of 10 people.

Amen - we always sit alone, but invariably when we sit at the Captain's table (which we don't do anymore), there's some boorish couple that you can't seem to get away from the rest of the cruise, let alone that evening. I like meeting people in the bar or by the pool where you're not a captive audience. And yes, all the people we have met & enjoyed seem to mainly be those who sit on their own for dinner. I think it's great that there's people that enjoy sitting alone & those who are more gregarious & wanting to meet others for dinner - that's what makes us the world go round.

And I'm with ScottC, nothing better or more romantic than a room service dinner on your private veranda ;)

One of the best cruises we've ever had we were seated at a table of 10 with a group of firemen and the wives on their first ever cruise. We had a ball, enjoyed seeing them in ports (where they visited firehouses and gave gifts to the local firemen) and generally enjoyed their cruise. Don't be afraid of strangers!

And you read FT??? :D :D

Have you ever actually done it?

An over generalisation. There are many different dining options available on many different cruiselines with tables of varying size to suit and even if you did end up at a table for more than two, then a word with the maitre d' immediately should sort the issue. I certainly wouldn't feel embarrassed about doing that.

:confused: Not sure of the point of this question. As others have said, everyone is different. I am sure the poster has lots of reasons for cruising.

Good suggestion by laf747 to visit Cruise Critic. Lots of info there.
