ATTENTION BANGKOK MEMBERS:
Anyone who entered thailand on a tourist visa entry <- meaning you bought a tourist visa from a thai consulate before you came here and were stamped in for 60 days when you arrived.
PLEASE BE AWARE; the online appointment booking system for Muang Thong Thani Immigration office to get an extension is totally booked ALL of next week already.
I checked EVERY day next week using the "Extension by Tourist Visa (TR) Issue by Thai Embassy or Consulate (TR60 - online1)" choice; the one that people on tourist visa entries that went to amnesty would use for any extension BUT all of the appointment slots are "redded" out meaning they are booked up. :(
I don't know what to advise you to do really. Sorry..
