My wife and I would like to visit the Strahov Monastery with the joint tour one day, in Prague. We would also like to visit the Sternberg and Schwarzenberg Palaces on another day, both in the same day.
For Strahov, the online ticketing portal doesn't seem to work for the joint tour. For the other two palaces, I cannot see the information on the ticketing portal in English, so I am not sure what to fill in.
Can we purchase tickets for all of these places directly on site the day of our visit, or would that be problematic?
Thanks in advance.
