I’ve been dancing on Crystal for 20 years, primarily on Symphony. Historically the bulk of the dancing on Symphony has been in the Starlite, nice sized wooden floor, deck 6, midship. Never in my experience was dancing in the Galaxy Lounge. In fact, the description ivyleaguegent gave in post #1 is of the Starlite, not the Galaxy.
Currently the bulk of the dancing is in the Palm Court. On Symphony the floor is big enough for waltz, foxtrot etc. What I don’t like about it is the extra movement caused by the location, the vast panoramic windows on occasion resulting in blinding sunsets, and a toasty room. The floor is not wood and is prone to stickiness in heat and humidity. (It was improved in the dry dock.) It is also isolated feeling. Us dancers were used to people strolling by the Starlite and watching us dance. it made us feel part of the community.
The duo is doing a good job. The backing machine gives a solid beat without overwhelming the piano and their voices.
Hopefully dancing will return to the Starlite when bookings support the additional musicians required.
