Most people who are not trying to live here on repeated visa exempt entry stamps will have little or no issue getting into the country EVEN if they have been here a couple times this year, as long as they spent time in their country or out of thailand a good portion of time before comin' back.
I think 'tourists' who come here
***
times a year, spread out over the year, who don't stay the full 60 days, who don't take the 30 day extensions are going to just skate thru passport control (But that is just my opinion)
Believe it or not a visa does NOT guarantee you get in to thailand 😮 All holding a valid visa does is make is so IF they let you in you get in for the number of days that visa allows.
There is no difference between the number of days you currently get on a visa exempt entry OR a real tourist visa you buy before you come here. BOTH get you stamped in for 60 days.
