We are ballroom dancers and did 4 cruises with Azamara this year.
To travel with Azamara we really enjoy, but not for dancing. It depends on the live band at Living Room, if they are able to play dance music.
With latin dancing it is a bit easier, but I remember we had some Viennese Waltz (because some blues or rock songs are 3/4) and a very few Slowfox and English Waltz.
In summer on Journey where more guests intersted in ballroom dancing, so I spoke to the CD and he arranged that Azamara Band play about half an hour, before the shows started, dance music at Cabaret Lounge, which was really nice.
