That's an understatement. I had a ball / a whale of a time there.
At current situation, whichever country (Thailand or Myanmar) opens first to tourists, I will go there.. Independent of covid, I will spend more time in Myanmar in the future (after having traveled all countries in SEAsia plus Taiwan).
Myanmar being less reliant on tourism, one would expect Thailand or Vietnam or Cambodia to open their borders for tourists first.
Currently, my greatest hope of getting back to Thailand soon is a vaccine or change in policy, e.g. requiring a covid test some days before people start their journey, then testing at check-in and again at arrival, and if all are negative or show that the person has had covid and is cured, let them in.
