One of our days in Barcelona falls on Nov 1 (All Saints Day), which is a holiday. I've checked open hours for various tourist sights and there doesn't seem to be much impact but I'm wondering how it might affect crowds at Casa Mila, Casa Batllo, Parc Guell, and the Magic Fountains at night on Montjuic. I've read that most shops will be closed but most restaurants will be open. Can anyone weigh in on what to expect on a holiday? Are sights likely to be more or less crowded? Will Metro and bus schedules be affected?
