Practical tips
Some island routes only run in the dry season (roughly November to April) or with fewer boats in the rainy season. Always search with your exact travel date.
Bangkok can have several departure points. Read the pier name on your ticket and plan your transfer to it in advance.
Luggage is often loaded on deck or at the front of speedboats. A dry bag for your phone and documents is useful, and a seasickness tablet helps on open-sea crossings.
