I used the wrong terms, I realize that it doesn't say 90 days but 3 months, that is the amount of time you can spend in the country with that type of Visa. Right now, I have a METV, they stamped me 60 days, but I can do 6 months with that type of Visa, I know that I have to get out of the country and back in. When I was in Pattaya, I used to do the Cambodia border run through a travel agent, 2,400 Baths at the time, probably more now, we left in the morning, came back in the afternoon.
