Does the Barcelona card let me skip the lines for some museums and the ticketed Gaudi sites?
If I need to book reservations in advance for Gaudi sites, how many days in advance do I need to do it?
Shall I see all of Gaudi in one day? and in what order and how much time between sites should I leave? (I hate not being able to be spontaneous and booking so much in advance before I leave!)
What other sites should I book in advance in Barcelona and vicinity?
