We switched from Carnival to Royal Caribbean a few years ago, once our son graduated from High School. Our last cruise was on Anthem of the Seas, in 2017, where us and another couple booked adjoining rooms on the 7th floor. We called Celebrity several times to ensure we had the same dining table and to see what needed to be done to open the door between our rooms. We were told Celebrity needed both of our permissions, which we granted on the same call. Fast forward two years and we are in the room we pointed to on the room map but our friends our 20 rooms away. Also, asked about our dining room and were told we were in separate two seat tables in different dining rooms. We were also told they had no notes of us ever calling in. They were able to get us a table for four at the Cypress dining room, but couldn't do anything about our adjoining rooms.
Our favorite parts of the cruise were the state room, the room attendant, the shower water pressure, always having available deck chairs anywhere outside and the entertainment and speakers.
The reason we won't be traveling again is the bar service basically anywhere not at the bar. We noticed several servers close to the bar but if you were 50 yards away or more from a bar, good look at getting served. Also being a beer nerd, the selection was about what you would expect at a local pizza joint. One craft IPA, which ran out after day 5 and a variety of all the normal domestic beers and imports. Although our waiter and assistant waiter were friendly and hard working, they obviously had too many tables to cover as it would be sometimes 10-15 minutes between visits. I would have poured my own tea, if I knew where the pitcher was. A meal that could have easily been completed in an hour took over 90 minutes, being topped off with a scoop of melted vanilla ice cream over cherries jubilee. I'm not a huge escargot fan but the escargot was the one dish that hit out of the park. Everything else was average or below average. Lastly, the ship has a rooftop garden, with a large screen screen for movies. Unfortunately, the person who designed the wooden reclining bench chairs obviously never sat in them. They are pleasing to the eye, but not to the body. That's pretty much my synopsis, beautifully designed ship but not necessarily functional.
The room and room attendant Jonathan were the best part of the cruise. We like to sleep in a cool room, and were able to lower the temperature to 66 degrees, which was comfortable at night. The big screen tv has a good selection of channels as well as streaming channels. There were a number of near first run movies that were available to stream at n/c.
