Dancersize Welcome to Desert Shadows RV Resort Dancersize page. At DSRV we have a very active Dancersize community that currently dances (exercises) three days a week in the Dance room at the San Jacinto Clubhouse.This activity is for everyone, and each person is free to dance (exercise) however they want. Our leaders are there to get the music going and encourage movement! We dance to the "Oldies" (1940's - 1980's). There is no wrong way to do this. We dance every Tuesday, Thursday, and Saturday at 9 am. Come on out and join us!
