That line for the Sagrada Familia was something else. Took us two hours just to get inside. The crowds at Park Guell were just as bad, couldn't even get a photo without ten people in it. Felt like you were just shuffling from one packed spot to another. Kinda ruins the magic when you're stuck in a tourist mob all day.
Remember my buddy trying to get that perfect shot of the dragon stairway at Park Guell. He waited forever for a clear moment, finally raised his camera, and a whole tour group in matching hats walked right through the frame. He just put his phone down and sighed.
