Booked 2 classes for 5 as a hen party activity, which included a free drink (Sol or a soft drink). We chose Bachata and Salsa, which started later than planned (the fault of the venue, not the class organizers).
The classes were great - started with a group warm up before splitting beginners and intermediate groups. If you don't have a partner to go with it's not a problem - they'll rotate the group around so that everyone gets a turn practicing the moves with a partner. The teaching was clear and at a good pace, and the instructors were friendly & fun. Definitely recommend!
