I am going to be staying in Berlin for two weeks later this month. I see from the bvg.de website that a number of different transit tickets are available -- like, daily passes, weekly passes, etc.
There are also two tourist passes -- the Berlin Welcome Card and the Berlin City Tour Card. These two passes seem to offer pretty much the same thing -- unlimited transit for up to five days and discounts at selected museums and other attractions.
Since the prices of the two tourist cards are very similar, which is better? Or, are neither of these worth it? I see that a regular transit pass (without the tourist stuff) costs pretty much the same, but is valid for seven days instead of five days.
