We just got home from our 8 day cruise on QE so I thought I'd post some info for others who might be wondering the same things I was when I originally posted this.
We had 3 duo bands, one was ballroom-oriented and supported by the 9 piece orchestra, another rock-n-roll oriented and the third was a scottish folk duo.
We had a fantastic time! We can dance all styles and so having 3 different bands on each night was just great. At 6pm there was recorded music. At 7:15 one of the bands would play in the Queens Room for 45 mins, then at 8:45pm another band would come on until around 11:30pm. There were a lot of couple-dancers and there was also a small group of sequence dancers. So the dance floor was often busy but at the same time there was still enough room for dancing without too much compromise (busiest around 9pm, outside these times there was lots of room). One of the afternoon teas was also dance-oriented with orchestra.
I had read other posts here saying that Cunard isn't catering for dancers anymore but I thought this was far from the truth, at least out here in Australia on QE. We were very well-catered for in my opinion, the dance floor was well-populated and everyone was having a great time. The only thing they have gotten rid of is the gentleman dancers (which is understandable because of Covid).
Also, a word about face masks. We got an email a day before leaving that face masks were now mandatory indoors so we were worried about being stuck wearing masks when dancing. However when we got on their policy was that face masks were merely 'recommended' indoors on board and only mandatory when embarking or disembarking.
We enjoyed our time so much that we've booked another Cunard cruise in a month's time, looking forward to it!
