Hi,
I was able to hear back from this wonderful group that for Salzburg and Vienna I should take a walking tour vs. HOHO bus due to the size of the city centers being small and compact.
It seems that Munich is much larger in size with more ground to cover so I have been reading about HOHO bus tours for Munich on Tripadvisor. From the reviews, it appears that the buses are old and dirty and that either the earphones or tour guide was not easy to hear or understand.
Can you tell me of your experiences with tours in Munich? It will be our first visit and we usually like to take a tour of a new city on our first day to learn as much as we can and then decide what to go back to on subsequent days.
Thanks for sharing any tour experiences that may be helpful.
Kim
