Just spent a one night at the JW using the ecert that came with the Visa. Because of the Summer the hotel was really quiet - the occupancy rate was in the 30's.
They didn't have an executive suite available when I checked in but was given one later.
The lounge had free non alco drinks available all the time. I didn't check the morning offering but the afternoon tea and the evening fair was ok.
Overall I would say that the hotel is nice but the rooms/suites would need some refurbishment.
