I also thought the salsa room at El Sol was mostly On2. Or maybe I was just watching The Presence dancing too much. But yes, I started each song On2 by default, and the followers seemed happy with the choice. All-in-all, I liked the level of dancing, and saw little 'attitude'. Can't remember one bad song. But I did like the bachata room music. Seemed like a mix of modern 'romantic' hits, cheezy pop songs, and traditional music. Like someone else mentioned about the Cuban room, the marble floor was far too slippery. Great idea to have inexpensive food for sale all night. Also the free wine from El Sol. But that was for us early birds. The one funny thing I noticed was a few women who looked like models, totally dressed-to-kill and made up, walking around the room in a group, and looking completely unapproachable (like VIPs in an exclusive 'normal' club, as I'd imagine it).
