My mom and I are headed to Vienna for 6 nights in December. I just ordered the latest Rick Steves Vienna guide, but it hasn't arrived yet. I have found that the advice in the guides for saving time (avoiding long ticket lines) and sometimes saving some money as well has been spot on. We want to hit the major sights and also attend Christmas concerts at MuTH and St. Stephens and a riding performance at the Spanish Riding School. I'll bet the guidebook has excellent advice on whether the Pass or Card are good values, but I don't have the book yet and would like to get the concert/performance tickets while there are good seats available.
Does anyone happen to know what the latest Rick Steve's advice is on this?
