Certainly, and often I like to sit out a couple of dances. It seems to me somewhat impolite to wait for half a tanda to go by before asking a woman to dance. So, if I am not sure of a certain partner and I only want to dance a couple of dances with her, 4-dance tandas sort of prevent me from doing that. With 3-dance tandas it seems to me easier to only ask for the last two dances. Sometimes it has nothing to do with a partner. If I sit out two dances and then feel like dancing again, with 3-dance tandas I only have to wait one more dance. With 4-dance tandas I have to wait two more dances.
