Just got off a 12 day Mediterranean/Adriatic cruise on Serenade of the Seas. After reading several recent reviews, I thought I would weigh in with a more positive experience.
Both embarkation and disembarkation were smooth, well organized and we felt we got on and off the ship in record time. The fact that we got on and off in the same port probably helped - no need to clear customs or immigration when we arrived.
We have cruised on Royal Caribbean previously and are diamond members of Crown and Anchor. We did make use of the Diamond Lounge for pre dinner cocktails and the continental breakfast. It was delightful to have a quiet spot to have our breakfast and plan our day on this port intensive itinerary. The concierges (Nizar the first week and Alan the second) were very pleasant and helpful - confirming dinner reservations and printing boarding passes.
We were in an aft junior suite with oversized balcony and panoramic views. However, there was a downside to this location - it is directly under outside seating area of the Windjammer. The noise from chairs being moved and serving carts began at 6:30 each morning. By the end of the cruise, we were so exhausted from lack of sleep that we were able to doze through the noise, but it is a real consideration when choosing an aft cabin on Serenade.One other cabin related negative - RCL has gone smoke free on their balconies since the beginning of the year. However, during sailaway from Montenegro, three men in the cabin below us stood on their balcony puffing away on cigars. We called guest services to complain and were told that "it is their balcony" - that is clearly not the policy; but guest services appeared reluctant to enforce the policy. We ended up having to move inside to get away from smoke.The cabin had excellent storage space and we loved the walk in closet. There was good space for relaxing with a comfortable chair and sofa in the cabin as well as two chairs and 2 loungers on the balcony. Our room steward was very responsive to requests.
