BTW is the walk-up rate comparable to the online rate? I am seeing a pretty good deal on the website, but as I don't know my schedule is going to be, I don't want to make a reservation now and realize later I only need a car for two days instead of a week. Besides, I hear that it's virtually impossible to find street parking in Munich, so I would like to have a car only on the days we are outside of Munich.

Thanks!
