try to answer!! Coffee is ok, best is when the bar opens at 10 and the cappuccinos are great!! you can get them AI all day! Malibu not sure about as I don't drink it but there were lots of pineapple based cocktails flying around when we were there! Loads of soft drinks..all the cokes and lemonades but also apple, pineapple, guava, orange juices as well as the fruit juice in the machines all day..my two teenangers had no complaints!
All mine did PADI open water diver aged 13, 16 and very old! I would think at 12 as long as he / she can pass the swimmming bits that would be OK. Why not e mail them? they were really helpful at Aquarius when we did. We had Hossam who was brilliant! They loved it!
Been to CSR twice now so any questions please ask!
