up to your case. too many exempt or visa run?

Following is for some who need to get TR visa.

don't do van or visa run. reckless driving, shit hotels and plus you can handle proces yourself, unless you have already got a warning by immigration.

As for getting tourist visa, pick Vientiane or Penang, up to your budget. plan ahead for scanned passport, photos, cash for "show money" etc for the process, including in and out(coming back to Thailand).

apply in Loas or Malaysia in evisa website, after you have stamped in your passport.

Have valid bookings for flight into Bangkok and hotel(not sure if showing house rental will make things easier or more difficult)

process will take 14 days at most, but usually it's 3 to 4 days.

then when coming back, be sure to have onward flight travel(either to your country or places like Vietnam. you can find cancellable ones. I will leave just at that).
