Perfectly understood Tod. Thank you for your clear answer.

I did actually tell the IO that I'd be leaving Thailand once during these 1st 90 days and he said to use a reentry permit.... since then new circumstances dictate that I must leave a 2nd time (unpredicted family stuff).

So I will purchase reentry permits for the time being….. then buy the multi when I get the 12 month extension.

Cheers and gratitude for sharing your knowledge!
