I need advice on Berlin passes. We will be spending three nights there- arriving on a Saturday afternoon by train and leaving on a Tuesday morning (so we will need public transportation.) We'd like to at least go to the zoo (we are staying at Pension Peters) and go to museum island. Which passes will be the most cost-effective? There will be 2 adults, a 14 year old, a 11 year old, a five year old, and a two year old.
Thanks!
