I had a long review typed out until my puppy jumped on the keyboard. So here's the short version.
1. Most people on the ship weren't overfed whiners like a couple of previous reviewers who were complaining about everything from fish salt levels to the crew's race (yet ignoring the line putting you up on their dime when the volcano messed-up travel). I found most to be down to earth, friendly, and approachable. Well-traveled and of good taste but not entitled and spoiled, wide range of ages from late 40s to 80s, maybe a dozen kids on the ship but all well-behaved. 2. Free alcohol goes a long way towards having a gooooood time.
3. Crew tried very hard to please. The butlers realized how quickly we were devouring the champagne and started leaving a fresh bottle ever night. The social hostess saw that our camera battery was low and sent up her personal charger. The maitre d'hotel sent us to the best table in the house after we helped him out (and I generally found the restaurant at least 2-Michelin-star quality.)
A. Shore excursions were generally very high quality with excellent guides, far better than the typical tour. Only problem was one tour where the "jewelry factory and museum" was actually a tourist trap gold shop. We visited there at noon and didn't have lunch until 3.30. On another, the tour company dropped us off at their rug store which had a big "Silversea" sign, which looked like Silversea was endorsing their subsequent hard-sell. In both cases the tour concierge had no interest in trying to make it better next time (such as eliminating the jewelry store and sending a message in advance about the rug store). She's been at sea a bit too long.
B. Breakfast buffet was a tad limited. The space is just too small and crowded to be a proper buffet. Try room service or wake up early and go to The Restaurant.
And if you're concerned about foxtrotting on the dance floor (per one of the earlier reviews), we did so for about a half hour and had no problems.
