Its easy because people dont want to go there. If people want to visit thailand follow the rules or go to bangkok and follow the rules there easy as that.
Not trying to be a jerk it just seems like people think its thier right to visit and to visit on thier own rules. I understand people might have relatives etc they want to visit but then you have to follow the rules. It might get more expensive thats sad of course and thailand is quite unlogical with thier rules and cant make up thier mind and changing its a pity.
