Barbara was absolutely fantastic! She was knowledgeable, funny and able to help us navigate in a way that maximized our time and experience. We would wholeheartedly suggest spending the extra money for the private early morning tour- skipping the horrible lines and minimizing wading through the masses on overcrowded group tours. We were able to see things that other tour guides don’t have access to and learned so much without feeling overwhelmed by trying to figure out what to see as there is SO much! We would absolutely book again with WIR and Barbara!
