Thailand’s cabinet approved a plan to re-open Phuket to tourism July 1, with a path to then re-open Chiang Mai, Krabi, Pattaya, Phang Na, and Koh Samui October 1.
I wrote, though, that you should wait to book travel unless you wanted to quarantine because it seemed likely re-opening would be delayed. Now, just two weeks after the plan to re-open was approved, it’s under consideration for (very likely) delay.
