We are planning to go to Siem Reap from BKK for 3-4 days by bus. It will not be an organized trip and we read all those articles about the scam visas and the long lines at the border station.
Can it all be skipped by getting an e-visa beforehand?
What is the process if with or without e-visa?
It is probably a very stupid question, but it's not clear that if I had an e-visa do I have to attach it to my passport (like glue it in?) or should we just give it to the officer separately.
Any other hints for making the border crossing smooth?
