No, have to print out the confirmation letter and I understand that this printout needs to be shown to the border officer when entering Thailand. I'm going back to TH on Monday so will know better by then 🙂
I travel anyway once a month so it works for me 🤷🏼♀️ But valid - it could have been cheaper if I had chosen group classes, or if I had taken digital nomad route which I'm also eligible for. This option seemed the easiest + I do Muay Thai anyway.
