I will be travelling around SE Asia and wasting my 30 day Thai exemption visa (UK) by going straight to Cambodia after a few days in Bangkok before heading further on the loop through Vietnam and Laos.
As I am not exploring Thailand before leaving for Cambodia, I will want to do that at the end for 3 weeks. 2 weeks in the south: beaches, islands etc... and 1 week in Chang Mai before back to Bangkok for flight home.
The problem is the visa as coming from Laos by land gives you only 15 days and I would need to try and get a 7 day extension from an immigration office(?) or pay a lot more to fly from Vientiane or where ever to Bangkok/Phuket to get a 30 day visa again.
What is the cheapest or best option? Or are there any other solutions to my predicament?
