We will put out a request as we have in the past for uncertainty:

If you or someone you know will be entering Thailand without a visa (visa exempt) tonight after midnight, please share your stamp so we can confirm the 30 vs 60 days.

You can post a photo of it in the comments, or send me a photo in a DM. We're just looking for verification if the changes will in fact be live on the 1st or not.

Thanks

*EDIT

We've received one report of a 30 day stamp after midnight. Awaiting a photo of the stamp and then we'll make a new post about it.

Please note that if we're able to confirm there is no 60 day stamp yet, do not expect anything to change until Tuesday as it's now a holiday weekend. But even then the PM's office said late June or early July, so we'll see.
