My wife and I are planning a family vacation to Cozumel in late June. My son and I dive already. My 14 year old daughter is somewhat interested in diving but not sure if she wants to go to the trouble to become certified. Does anyone know if a resort course would be the way to go for her? And would it allow her to go along with her brother and I on a dive or two? We are staying at El Presidente. We thought about diving with Scuba Du. Any suggestions? Thanks.
