Pretty much like the modern Bachata/Salsa scene in Europe. Large parties that go from 11pm to sometimes 6am in the morning. Very little alcohol consumed but you pay big to get in to cover the cost of the location and dj's. However many venues will body frisk you for water bottles in an attempt to force you to the bar to buy drinks. At least one large event has stopped that and now provides free water ( https://bachata-fest.com/ ) under the obvious realization that people are there to dance not get shit faced and that bag checking and frisking for water bottles just leads to bad community feelings.
