We've never cruised though I know lots of people who do and love it.I think it's ok if you see it as a relaxing holiday rather than' 'travelling' and being exposed to different cultures,talking to the 'natives'which is what we like to do.All our European holidays are self- organised and we tend to spend several days in a city /country to 'get under the skin' of it .(sorry if that sounds pretentious Its not meant to )We have however done several long haul coach tours but you do get a reasonable amount of time in each place and you do see places other than those on the coast-that's the aspect that that would frustrate me,having only a few hours at each destination, and I know DH would stress about being back at the boat in good time.It's harder to miss a coach !But not having to constantly unpack would be nice .On any holiday ,except the really casual,most people would make a bit of an effort in the evenings surely ?.If we eat out when self catering,from Cornwall to Cumbria ,we would change after a days walking or sight seeing . .Certainly people do when I've been touring .Its nice to have a shower,put something pretty on and relax in a pleasant dining room.And we would do that even if it's just us
I know one couple who love the dressing up aspect of cruises-Dinner jacket and cocktail dress(I dont think anyone wears a ball gown anymore even on QM2)I think it makes them feel aristocratic and rich (they are very well off but not rich) and I'm sure they name- drop other cruises they've been on to fellow passengers .It's part of the pleasure for them though,and harmless enough ,though she says (rather sniffily) its getting more and more casual
