Questions & AnswersAsk a question
Just looking for a getaway :) None of us (myself, my husband and my daughter - 17) have our diving licences - yet :) If we come diving with you, would you recommend doing the PADI ELearning first? If we were to visit Grand Cayman for say 7 days - how much time would you say we could get in ?

I agree if you want to enjoy the island any thing you can do ahead of time will cut your lesson time. This will give you time to enjoy a few dives after your open water testing

Hi, staying at Sunshine Suites 2/12 until 2/19. Where are you located? Is there transportation to your dive pick up? Have used Red Sail before. Cost for 2 tank dives? Would like to dive 3 days with a possible night dive. Thank you. Wayne

Hi Wayne, we are very close to SS and our 2 tank rate is 110. Yes we can arrange a pick up. Tom
