Thank you, guys.
I'm convinced now after reading your posts to leave the car at the hotel. Less stress (for me and other drivers) and more sightseeing (the main goal)! Funny, as I am a software developer for public transport industry, and I usually encourage people to use more the public transport.
And the car wouldn't be compatible anyway with some beer tasting...
for the tips. I will add the places you mentioned on my list.
