We were on Equinox last week (end of August) and I went down to Al Bacio to check out the bubbly situation- they offered me a glass to be charged to my sea pass card!!! It's not a big thing but just indicative of the general trend.
The service in the MDR was very, very slow- our waiters were working hard to serve the tables but the food just wasn't coming out of the kitchen.
On the plus side we got chocolates every night and the afternoon canapes were better on this cruise than others.
We enjoyed ourselves but, as others have noted, the experience has changed.
