You are welcome. Happy to help. I've been to Prague a few times and love it. Such a special city. If you are into history, there's an old movie called Operation Daybreak. Set in Prague and when you are there you can go to the church where the end of the movie is set.
If you get to the towers in town (Astronomical clock, Charles Bridge, etc) in the first hour they are open you can enter for half price. If you get to the Golden Lane in the castle complex after 5 pm, it's free to walk down it. Before then you have to pay.
