I would speak with one of the guys that cleans out the toilet bores, they can suck allmost everything for a low cost, when they do our place it is usually arund 250-300 bath. Just a suggestion.
It sounds like you live in the countryside.
Hope it will work for you.
Haha. Now i know why i didn't want to go to Cambodia. I only used the train to Bangkok because it was more convenient, and the train ride wasn't that bad.🤩
2 train every Day. Only 3rd. class, but cheap less than 100 bath per person, all the way to Aranya Phrathet. 5-6 hour ride from Bangkok.
Stop at every station.
Good luck.
You can buy extra days, 3bath for 30 days.
Dial *113*90*9# This code will add another 90 days to your number.
If you only want 30 days insert 30 instead of 90.
I am not sure if you can surpass 1 year, but I suggest that you prolong the days just before you leave.
PS. You an buy up to 180 days in 1 go just put 180 where 90 is.
