Saladan Hotels
Saladan is one of the main 'cities' on Lanta. It's where all the ferries from other parts of Krabi dock, as well as where many dive boats and day trip speed boats depart. Saladan doesn't really have much beach to speak of, so unless you plan to spend a lot of time diving or making other offshore day trips, there's not much reason to stay in Saladan, which is why there are so few offerings to choose from.
Another quite comfy option is Sincere Guest House, which is very close to the ferry pier. Set over the water of the channel, the guest house is a nice place to spend a night or two 'in transit'.
