I've just come back from a week in Pattaya.
No mention of Vax status at the hotel upon checking in or anywhere else I visited.
I heard that you did need to show proof of Vax to enter the music festival arena.
Many people not wearing masks when out and about but some shops request you do.
Generally busy at the weekends for bars and restaurants but Mon, Tues, Weds was alot quieter.
The Indians didn't really seem to be in one specific place but around most of the town.
I stayed just off Soi Buakhao and they were visible in the street but not in the bars and they usually stick to their own restaurants, run by their brothers.
Definitely alot busier than my previous visit in April, quite a few Aussies coming in when I was there.
Enjoy.
