I'm not being a cheap Charlie, I don't use land crossings if I need to do a border bounce, I fly to Penang or somewhere and enjoy the day there. It's not my fault you left it late lol
But when I did it, it was to apply for a new visa. And I was across the border the same time as everyone else, including those who were in your situation lol
I'm sure when I went to Vientiane and Suvanakhet everywhere except THB with no extra charges.
I know you said it was easier with the fixer but I genuinely don't see how. You just do the same thing as they did but on your own. Taxis and tuk tuks would probably be cheaper too
