I went to buy tickets to Casa Batlló for our September visit. We're going to Sagrada Familia first (9:00 tickets) and I have no idea how long we'll spend there.
I assumed that if I bought the fast pass ticket for 28,50 € that I could enter Casa Batlló at any time, without waiting in line. But it requires me to choose a time. Do they actually enforce the time slot?
I also see Open Date ticket for 30,50 € but when I choose that, I can add fast pass for another 5,00 € so I assume that if I don't, I'll be waiting in line.
Any insight on this or recent experiences?
