While on the Thai pass for visa exemption for test and go, after you leave the test and go hotel, and go to the next hotel, is there any special proof you need to show the next hotel that you in fact completed the test and go stay + test? Or do they look that up in a database with your thai pass or passport ?
TLDR : Answer Summary
When transitioning from a Test and Go hotel to another hotel in Thailand, guests generally do not need to show proof of completing the Test and Go program, as they are free to move about upon receiving a negative test result. While hotels may inquire about vaccination documents, there is no requirement for a completion certificate from the Test and Go hotel. Some travelers may carry their vaccination proof as certain establishments might request it.
