But you still have a void stay in Thailand even if your personal benefits it’s more important than to fulfil the requirements for a legal stay in a country you choose to live.
I understand. Still a tourist entry though but it’s slightly easier to get approved with a formal document. As said personally I would have considered to use a landborder transport company. They’re fairly priced (3-4000 baht), know the "name of the game" and wouldn’t bring you unless they’re confident in getting you another visa exemption.
To avoid going back to back on visa exemption I guess. As said can slightly increase odds for a "clean" entry. Personally I just would have used a landborder transport company to bounce me for another 60 days visa exemption if that was the point.
Then I’m not sure if I got your question, but a Tourist visa has been 60 days for a long time and is still useful for people who are not entitled to visa exemption or if the exemption is turned back to 30 days again. A tourist visa can also slightly increase your chances for a new short stay entry in fact only because it’s a formal document. Both gives you a 60 days stamp and permission to stay for 60 days upon arrival.
Yes you can apply for a single entry tourist visa through the embassy/consulate that serves your area even though you’re not a resident of the actual country. Check with the particular embassy, most allow applications from foreigners.
