For those of you not in beachfront accomodation and like to use sunbeds there are some for rent just north of La Own Khao Lak resort -150B per chair - they also have cold drinks etc available - they seem to be situated in some sort of vacant land. (I am not sure how you accessd the area but it is about a 10min walk along the beach from Nanthong Bay Resort). In addition to that Coconuts Restaurant (Next to Nanthon Beach Resort) have beds you can use if you buy food/drink but they are cramped together. There are people on the beach selling an air bed type thing that seems popular.
This is an info only post
