It's currently much better than that, February 2024 tourist numbers were 3,352k compared to 3,601k in Feb 2019, so now recovered to 93% of 2019 even with the lower rate of Chinese.
Interesting to see those high occupancy rates at hotels commanding 5k+ baht per night, seems like wealthier tourists are in fact visiting Pattaya and Thailand in their numbers contrary to what some on here believe.
