Destaques or floatees are the people who populate a Carnival float. As each school can take only 6 to 8 floats to the parade, positions are actually quite limited. Each float has at least one main destaque. The other floatees are divided in groups, with different costumes and functions. Each group may perform a special choreography or some act together, rehearsals are mandatory. Depending on the complexity of the role, samba schools may select only professional actors, dancers, even circus performers.
