I booked this one at the last minute (a week out) and with a bit of trepidation since we're Celebrity first timers and the sailing was 10 days long..
Our biggest concern was avoiding withering stink-eye from the masses on "Chic" nights, as our cruise attire is typically very casual, and we're not dining room people or show-goers.
I'm happy to say that we experienced no such shaming. To the contrary, all fellow cruisers I interacted with seemed very chill and just happy to be on vacation. That was a relief.
The staff was friendly and helpful. We only ever ate at the Garden Cafe, so I can't speak to the food quality of dining room or specialty eateries. We loved the Garden Cafe! Aesthetically, it felt spacious with plenty of seating. The walk-ways were wider than we are used to on HAL or Carnival, which was nice. There was a good variety of food options and everything we had was far superior to offering we've had on other lines. One exception was a tough piece of minute steak I grabbed, but that can happen and could have been easily dealt with if there had been any steak knives available (why aren't there?) The biggest pleasant surprise was the PIZZA!!! Some of the best pizza I've had....ever....and I've had a pizza or two.
We loved the variety of seating all over the ship, for the most part....some seating was apparently built for NBA basketball players as the horizontal seating surface would require thighs of a length not found on most humans in order to sit comfortably.
Overall, the Silhouette is a fantastic ship, and Celebrity is now another cruise option for us. Already looking for a future cruise...
