We have just returned from a wonderful Adriatic cruise on the Silhouette. I'll try to highlight some of the postive points and issues that I would have wanted to know in advance of taking this particular cruise.
The Ship: The Silhouette is beautiful and in excellent condition. I thought there was interesting art throughout the ship, but didn't leave myself enough time to just hang out and enjoy it. Our voyage was very smooth and everything seemed to 'work': we left on time, activities were well-organized, and I didn't realize there were propulsion issues on the ship until I read about them on Cruise Critic after the cruise was over.
The cabin: we were in a concierge class room, which was kept clean and everything was attended to appropriately. We even had towel animals! I suspect we may have had a change in stateroom attendant after a couple of days because we didn't see our original attendant (Antonio) during the later part of the cruise. In any case, though, the room was consistently cleaned and perfectly maintained (whoever was doing it). Re concierge class: the cabin location and balcony stools were great. the canapes are gross. The fruit is nothing you couldn't pick up yourself around the ship. There is an actual concierge who seems like she is very sweet, but we didn't need her services. No flowers anymore. There was an upgraded totebag with black handles.
