I agree with Charlielyn that the Gran Ventana does not seem to get large crowds of teens without parents. We have stayed there 6 times but not during March Break. We have been there however during Easter and during Christmas/New Years.
Without a disco on site, most young people tend to go to Roadway, Hemingway's or to Holiday Golden Village to Mangu at night.
Never had a problem with rowdy behaviour. You can check out our photos at:
