Better to have your own mask with subsciption which fit you. The rented ones are all without any subscription.
The subscription mask is around ~HK$700 in HK.
I don't think wearing a pair of "con" is suitable in diving, as u can loss them easily.
Must try the BBQ seafood in the Alona Beach at night.... I still remembered my BBQ barracuda, which was not always available. Rent a car to see the Chocolate Hill, big-eye monkeys etc are the must activity. Also, u can try the Chinese foods of crabs and steam fish in 香滿樓. Food price is very cheap.
U can rent the car at the dive shop, or at the tourist centre. Rental price depends on the kind of car, and number of people. I rented the dive shop owner's own 4-wheel dive with a driver so I paid more.
