not sure if you are really close by it wouldn't hurt to try. If it's not crazy busy I don't think they would say anything. But it also depends who you get and is fussy or not.
Went this morning quick and easy . Took 30 minutes hardly anyone there. Need to make appointment. They send you email check your spam it's 2 forms. They ask for copy of appointment from online. Got a under consideration stamp to go back in two weeks. They did want to show proof of where I was staying since my hotel didn't register me but I had print out of my receipt of stay as I been living in hotel the whole time here. In and out fast no questions asked just paid the 1900 baht
