What is a consulate/embassy run?
A consulate run is when you physically need to get a new Thai visa in your passport and that means schlepping to a Thai consulate/embassy in a neighboring country.
It goes without saying that consulate runs are more expensive, more time-consuming (and dare I say more stressful) than border hops.
Depending on what time of day you arrive, Thai embassies / consulates will issue you a new visa within 48 hours.
