Don't get ripped of by the yellow shirt guidances outside of every hotel. In the past they used to be for free and every guidebook is still refering to this. However governmental support stopped.

We did a two hour walk without noticing that we had to pay 20 euro per hour. At the end we driven into a corner by this group. After big discussion and threaths we payed 25 euro's. Police is aware of this issue but cannot do anything about it.
