We just got home from a 10 night cruise to Canada, the Maritime Provinces and ports in New England. Because of a severe storm, we did not get to see the Maritime Provinces. One cannot fault the ship or crew for that.
The food was very good, sometimes exceptional. The food and beverage service was excellent. The butler and maid were exceptionally good. The enrichment lecturer was knowledgeable and friendly.
A few minor quibbles: more than one outlet would be nice for charging all the stuff that needs charging; ESPN for football and baseball, better communication from the cruise director.
The biggest problem is cigarette smoke. The published policy is "smoking in certain places." Certain places include the starboard side of the main bar on Deck 5, and the starboard side of the pool deck. The problem with this is that there is no barrier between smokers and the rest of the bar. So the smoke gets out into the whole bar and the adjacent corridor. The published policy about smoking in the suites is that smoking is not allowed. However, that policy is not enforced. There were heavy smokers in the suite next to us. The housekeeping staff is not allowed to enforce the official policy. I had to go to the concierge desk and complain, rescue inhaler in hand. Yes, I did have to use my inhaler for smoke-induced asthma. The smokers did reduce their in suite smoking somewhat after that. It wasn't just one suite; I could smell cigarette smoke in at least one other suite from the corridor. And that was just one deck.
If you have to go, avoid Deck 5. Sit on the port side of the Restaurant. Complain if there are smokers in a suite next to you.
As for us, we will not return to Silversea.
