We did this very same cruise last year when it was the Splendour of the Seas, and booked it again this year (early and paid much more than many guests we met) as we had loved it and rested and relaxed for a whole week in great weather.
On the positives of this cruise; we witnessed some excellent members of staff; the cabin was fine (very good bed and pillows and shower); the weather was excellent with the exception of the one day at sea and good specialty restaurant in Chopp's. We watched two movies outside on Deck 9, under the Arabian evening sky and it was fantastic (although blankets were no longer available to keep us warm).
This time however we had a few more concerns and saw real evidence of a number of cut backs from Royal Caribbean from last years cruise.
The cabin was fine (very good bed and pillows and shower). Dirty cabin doors into the balcony. Black mould at bottom of doors.
Biggest disappointment/issue was that sleep was so difficult because of our cabin's location. We could hear clearly every word of every song from the Schooner Bar below us, from 10.00am until after midnight. The microphone on the piano in the Schooner Bar was 44 paces from the Level 6 lifts. Cabin 7620 was 45 paces from the Level 7 lifts!
Sleep was impossible until after midnight. Not good if you have gone for a resti and a chance to catch up on your sleep. As we did!
