Did a search and didn't come up with much about local transport, i.e., seelors, samlors, tuk-tuk's, prices, availability, etc. Will there be plenty of seelors going to and coming from most of the tourist venues? Shared and hired.

Been quite a long time since I was there, but I do remember a regular songthaew service along the main roads. Just flag it down and jump on.

There were a few samlors, but I never like them - always feel like I'm exploiting some old guy pumping the pedals

Of course, there are motorbike taxis, and the places I remember them, they had fares posted on signboards.
