This sounds like an interesting event - I might even join in since it's more of a group dance.
From their website: Gustavo will be teaching the basics of Miami-style salsa in the format of rueda. What makes rueda style different that other styles of salsa is that the 'pressure' of one-on-one dancing is relieved as the dance is focused on the group as the whole as you have to work together to create the dance. Rueda allows everyone to learn the musicality and standard moves in a fun and often hilarious way through group calls and interaction!
