All good responses. Can’t really add much other than to say that your requirements will be met on SS: interesting places, very good food (not quite exceptional IMHO), martini in hand with jazz in the background. The SS experience is mostly on par with Crystal but with a few differences. Entertainment and enrichment was superior on Crystal but the standard suites are larger on SS. Most of SS ships are newer and very elegant. No annoying photographer. I would not categorize either as an ultra luxury experience, though. Now that you know you want to cruise in a certain manner I think your needs will be met on SS, SB or Regent so perhaps your focus could be on itinerary.
