It's Labour Day weekend and as Labour Day falls on a Sunday this year, Monday will be an 'in-lieu' day holiday. The secret? Jomtien Immigration will open on Monday and very few people will be there as they assume it is closed for a national holiday. Get in there..... and out again super fast.
Note - Jomtien Immigration, (and we assume all similar departments countrywide), will be closed from Wed 4th May to Sun 8th May for the Coronation Day holiday. We recommend you don't go to Immigration on Monday 9th May if you can help it, it will be manic.
