I find information on Hallstatt... however, I do not see this town on the itineraries for 2025
I don't think so.
The https://www.ricksteves.com/tours/austria/munich-salzburg-vienna-tour
used to stay 1 night in Hallstatt. I believe they changed the tour this year because Hallstatt has become so over run with tourists and lodging has gotten very expensive.
