I had to queue from 08.50 to 11.00 just to have a number for tourist renewal. Retirement waited even longer. Apparently you have to go veery early like 04.00 to 06.00 am to get a ticket... Good luck!!
I have a question for you : if I already entered Thailand twice by land this year with a visa exemption, can I enter once more by land with a 60 day tourist visa this time? Thanks!
