Absolutely! Basically, especially Phuket, Krabi and Samui are just perfect hubs from which to explore the surrounding paradises.
If you don't do this, you're missing out on the best: the indescribable beauty of Thailand away from the hustle and bustle above and below the water, the experience of freedom and closeness to nature of tropical sailing adventures, the real Thailand with its original facets that you can only find on deserted islands.
In addition, for many, booking multi-day private yacht vacation is a welcome change from boring hotels and resorts. No 5-star accommodation can compete with the splendor of the starry sky. It is an experience of pure luxury, unforgettable and varied days that cannot be experienced anywhere else in the world.
