They asked me when I want to leave so it sounds like there is a longer option.

It was not a pass, but a recipt to collect my passport and it just said single day journey.

UPDATE:

The border was as

@Tod ********

and the rest of you said, I stamped out of TL, walked across the bridge, asked for a 1 day pass and paid $10, they held my passport and got a receipt. Few hours later I came back and collected it, it had Myanmar stamps in and out.

Then stamped back into TL on 30 days exempt.

Did it 2 months ago. Every thing went smoothly. Stamped out of thailand, got on a boat (50baht) , paid $10usd to get stamped in and out of myanmar,then spent a few hours in myanmar then then came back by boat (50baht). Then got a new thai 30 exempt stamp.

Btw can anyone reccomend a safe place to park a motorbike at the border?

When I crossed at ranong I didn't get any physical pass or any proof, just the regular entry and exit stamps next to each other at the same time.

Thanks for the responses!

I see, so they hold your passport..

My confusion was caused from my assumption that it would be like the procedure at the ranong/Myanmar border: where they just stamped me in and out of myanmar at the same time and handed back my passport and left it to me to make sure I leave.

Good to know. =)

I'm try to find out how many Myanmar crossing points will let me pay $10 for 1day pass and get 30days exempt stamp upon return.

I will be touring the south to the north on a motorbike and want to use my 2 land crossings before 2018 and then 2 again before I return to the USA in April.

$10 usd is cheaper than 1900 baht extension or any other alternative I am aware of.

3 possible crossing locations into Myanmar, mae sot, mae sai, and ranong.

Thanks! so it sounds like there is a total of 3 possible Myanmar crossings for 30day exempt stamp purposes.
