Does anyone have recent experiences with making a re-entry permit at Don Mueang (DMK) airport before the flight out?

I have a 60-day tourist visa entry, but would like to get out soon (only 10 days in) without forfeiting the rest, but don't want to waste a day in Chaeng Watthana. Been there once, and would rather burn the entry than suffer that place again.

Reading some old treads, it seems like there's an office behind immigration desks, staffed 24h, but most reports are 2+ years old, so it would be good to get a more recent confirmation. Does one need to get stamped out first? Does it take a long time to do the re-entry permit? What is the cost (some say 1000, others 1200), and is it necessary to prepare all documents first?

yes, right past immigration as u walk out take the right an u will see the office on ur left

1,000 for signle

3,800 multi

u can get application there but make sure u have a photo an copies of ur

index page, current visa in passport

in country u need copy of ur departure card but u wont have that after immigration.
