A transatlantic cruise was on our "bucket list." It was a truly enjoyable experience. Even at five years old, the Equinox still looks like a new ship. Much care is taken to make the ship look pristine. The Solstice class ships have the absolutely nicest public restrooms. Also, the global staff was professional, courteous and even fun. Embarkation was a snap. We got there at 11:30 and literally walked on board. While the rooms weren't ready yet, and the announcement was made that we would be able to get in at 3:00 p.m. Exactly at 3:00 p.m., the announcement was made that the rooms were ready. We had opted for Aqua class. Unfortunately, even though we had been told otherwise, our original stateroom, 1556, had a window-washing ladder across the entire top of the veranda, pretty much obstructing the view for anyone over 5 ft tall. We complained and were told to come back after the ship had sailed. We were fortunate that someone didn't show up and were able to get another cabin (1508), which was lovely.
We also bought the three-restaurant dining package. The first night we went to Tuscan. It was fabulous. Probably one of the best filets I have ever had. My husband had a ravioli appetizer with braised beef and mushrooms. Awesome. We also went to Silk Harvest (excellent duck) and Murano (the atmosphere was wonderful and food terrific -- maybe a little rich for my taste -- but that is what you expect in a French restaurant.)
We loved Blu. I believe it is well worth the extra price. We never had to wait to be seated, but did see a short line one evening as we were leaving around 8ish. We did go to the MDR one night -- and agreed that Blu was far superior.
Eight solid days at sea is probably not for everyone, but we were fortunate that we had mostly beautiful weather and moderate seas. Sitting on the veranda and watching the ocean was sooo relaxing.
The ports, Ponta Delgado, Azores; Lisbon; Seville; and Gibraltar were great. Disembarkation was also a breeze. Since we had an early flight out of Malaga, we walked our luggage off ourselves and had no issues at all.
I would certainly do a transatlantic again, only in the opposite direction. I want to get back the six hours we lost by having to set our watches ahead. :)
