The tour lead by Eric was good. We learned much from the tour.
1. We were new to Munich and the tour did not end in Marienplatz, where it started. We have a hard time finding our way back even though Eric did tell us how to navigate.
2. Unfortunately, there was a computer glitch at the time we were booking the tour, we end up with 3 bookings. Viator was fast and efficient to process the refund after I made an international call to their US office. However, due to the exchange rate, we were made to pay a small sum for the computer mistake.
Tour guide was great, explained a lot of the history and backstories of everything. It was great seeing so many historically significant locations. Guide had a great open mind about the whole experience.
