In terms of the structure of the day, there really is no difference between the two. The difference has to do mostly with scheduling and commitment of time: campers registered for a week-long performance camp commit to a full week of camp (Monday through Friday) and participate in a showcase performance for parents at the end of the week. Campers sign up for sampler camps on a pick and choose basis, so a full week commitment is not required. There is also a half-day (morning) option for the sampler camps.
