We left at 5:30 in the morning from the Queen Victoria Inn offices on Soi 6.
We arrived at the border at 9:30. We completed all the procedures and at 10:15 we were already in the van returning to Pattaya.
We stopped for lunch from 12 to 12:30 and arrived back at the offices on Soi 6 at 2:30 p.m.
Just enough time at the border for an agent to accompany you to the queue outside Thailand, stamp your passport, walk across the border, get to Cambodian passport control (where another agent is waiting for you), stamp your entry into Cambodia, stamp your departure from Cambodia, walk back across the border, seal entry into Thailand and return to the coach after a quick visit to the bathroom.
In fact, since I was in Cambodia I would have liked an hour free to see something, even if it was a market, but everything went very quickly and almost without queues.
There was no need to pay anything there at any time, not even the entry visa to Cambodia.
We made a quick stop on the way to Cambodia to go to the bathroom and have a quick breakfast (not included in the price) and on the way back to Pattaya we stopped to eat at a restaurant. The food was good and was included in the visa run price.
