You just omitted the larger majority of Latinos that prefer and dance Merengue, Cumbia and Bachata .
These 3 have now been widely accepted into the " fold "... particularly Bachata , in the non latino community .
If you add salsa , mambo.. .. and bolero,, bingo ! SIX dances .
My suggestion would be this to the estab. Soc. .. form an indigenous latin section ( they already have added salsa )
