Hi I live and work in cayman on a work permit from the US. Go with a small boat operator and let them know the skill level or your youngest daughter. I work for Petermilburnsdivecayman.com and help out on my slow days with Dusty at divenstuff. We carry no morethan 6-8 divers and offer very personal service, care and attention. My goal is customer service. This week already I did one on one with 3 newly divers on different days and stayed very close and they all appreciated my help. I even had a customer tell me she had never received better service on a dive boat. So try us out. peter has been working on island and diving for over 40 years. We offer hotel pick up. Hoping to meet with you and help your family have a safe diving trip.. Lisa PADI, NAUI, DAN, EFR instructor and mom
