Query: A definite must have if going to Poland

I bought this for our daughter's trip to Poland through her University. She hasn't taken the trip yet, but she browsed through the book and can't wait for her trip. It looks very helpful in finding everything you would want/need. My mother-in-law also bought this for their trip to Poland a few years back and suggested it to her. A definite must buy!
