Arriving into Bangkok today with test and go, extra document to fill in on arrival, keep the pink slip as this is for your 2nd free pcr test, immigration needs to see booking of hotel after test and go
TLDR : Answer Summary
Travelers arriving in Bangkok under the Test & Go program should prepare extra documentation, including a pink slip for their second free PCR test, and must show their hotel booking upon immigration. While some travelers reported not being questioned about accommodation after the first test, others noted the efficient processing at the airport, taking around 20 minutes. Several discussions highlight inconsistencies regarding the pink slip and the communication about the second PCR test across different hotels in Thailand.
