Will be arriving early in Prague and looking to book tours in addition to the ones offered as part of the cruise. I know that the Prague castle complex is fairly large and you could probably spend additional time there. Is it worth an additional tour and/or time to cover more of the complex than what is schedule on the cruise (which includes St Vitas and Strahov Monastery) such as the golden lane and St George's for example? The itinerary description is a little vague. Best Regards
