Booking a diving liveaboard cruise or daytrip is a very simple process. However, our partners have their own requirements regarding payment of deposits and cancellation scenarios. In most cases for liveaboard cruises, a 30% deposit is required, and this is usually 30% of the trip price, not including the national park fees. Some of our day trips only require a 20% deposit, while others ask for the full amount. Safe payments are most easily done via PayPal, even if you do not have a PayPal account. Any internationally-recognized credit card is all you need.
Please note that if you haven't dived in the last twelve months, PADI and SSI diving centers, including liveaboard boats, require you to take part in a short 'scuba review' dive which includes a very small amount of practical skills and theory. This is necessary, and in order to avoid spoiling your diving experience. Diving at the Similan Islands is done far out at sea and it is far from ideal for your Divemaster to find out that you need some help after it's too late.
