Does anyone know if it accepts Sachsen Tickets? It's a bit of a tourist sightseeing service, but on the other hand it isn't at a particularly premium price. The website doesn't say yes or no. The DB website doesn't mention it specifically as valid, but it is run by the Dessau local transport company.
No, according to this: https://www.vvo-online.de/doc/DB-Broschuere-Sachsen-Ticket-Streckenkarte.pdf
Thanks for finding that.
I really enjoyed walking through the garden realm at Wörlitz. Make sure you write a good trip report!
