Having fun while dancing with two ladies can be pretty problematic for any salsa dancer. Why is that? Because both ladies should receive the same amount of attention and leading. 

The more intricate the dance patterns, the more difficult it is to pay attention to both of them. One idea could be to lead one lady into a simple turn or a cross body while the other is doing her basic step. For an upper level, the guy can lead both ladies at the same time into different moves, making the dance even more fun while raising the challenge.
