Is Sihanoukville worth staying in?
For many travellers, Sihanoukville is more of a gateway than a destination. Use it carefully for island access unless current conditions and your specific plans give you a good reason to stay.
Answer
Sihanoukville is one of the Cambodia stops where old advice can age badly. For many independent travellers, its practical role is getting to and from the islands, not being the highlight itself. That does not mean nobody should stay; it means the reason should be specific, current and tied to your ferry timing, hotel choice or onward route. Do not give it nights just because it sits on the coast. In Cambodia, not every coastal stop is a beach holiday.
