As nobody has been able to shed any light on your question I thought that maybe you might be able to tell us if you are staying at a hotel in Krabi when you return from Railey. If so I would be asking if you could leave the vehicle at the hotel where it would be a lot safer. If not I can only say that you will definitely be able to park somewhere near your departure point but as to whether the car would be safe that is anyone’s guess. I would probably be trying to park somewhere that is a more built up location and you would really need to see when you arrive. Good luck and let us know how you go with it.
