I used Agoda but as soon as I received the Agoda confirmation email I emailed the hotel. They took about 12 hours to reply but their reply included their booking reference and stated inclusion on Transfer, PCR test etc. So I screenshot their email and used for TP. It was accepted and I received the TP QR.
Booked a BKK Test & Go package with Agoda. But in my TP application I used a screenshot of the confirmation email from the hotel which states package including transfer and PCR test etc. This email contained a different booking reference. The hotelโs reference is the one required. I received QR code within 15 minutes. .
