I've found this site quite useful for finding information about the Thailand Reopening schemes and hotels.

https://thaiest.com/

They also have a facebook presence https://www.facebook.com/thaiestcom

I have no connection to the site/business, but it's been a useful source for finding info about the 1 night hotel + transport + PCR Test packages needed for entry to Thailand under the Quarantine exemption scheme, and one of the most up-to-date sources I've found so sharing as may be useful to others.
