Any opinions on which route for the Prague castle I should opt for :
Prague Castle – Circuit A
Prague Castle – Circuit B
St. Vitus Cathedral, Old Royal Palace, St. George's Basilica, Golden Lane with Daliborka Tower
Prague Castle – Circuit C
Exhibition The Treasure of St. Vitus Cathedral, Prague Castle Picture Gallery
Please suggest bearing in mind, we will be travelling with my parents who are old and have knee problems.
