We cruised on the AmaSerena in July 2019. Our embarkation was very smooth. We were allowed on board early and had a light lunch available. Our room was excellent. We were in room 306 - we had a nice balcony and a very roomy bathroom.
The dining experience was excellent. The food was great and plentiful. Plenty of options for a vegetarian in the party.
We enjoyed our shore excursions, especially the option to be in the Active walker group, which gave us more (and faster) walking.
Cabin was plenty roomy for 2 people. The bathroom was a big surprise, as my only experience was ocean cruises. There was a large shower and lots of counter space. The balcony was very pleasant, although we spent most of our outside time on the sun deck.
