What details do I need for a guarantor when applying for a tourist visa in Thailand, and what should I do if I don't have one?

When applying for a tourist visa to Thailand, you typically do not need to provide details of a local guarantor, as tourist visas can be processed without one. If you do not have a guarantor, you can simply leave that section of the application blank. Some sources suggest using your first hotel as a reference, but this practice is becoming less common, especially due to the increasing adoption of online visa applications.
