I'm driving to Aranyaprathet to cross the border and I plan on leaving my car in Aranyaprathet. Is there a safe place to park my car for 3 days while I'm in Cambodia? Are there any secured parking lots and if so how can I find them if I don't speak or read Thai?

Moved to motor forum.

Drive right through the town and head to the Markets, there are signs telling you where the big market is.

Drive into the market and right through to the back and you will see a secure parking lot where the coaches are parked and being washed. It's a 100 meter walk to the border.
