I am planning my trip for my visit to Barcelona in less than two weeks. I want to buy tickets for Park Guel in advance and wonder if there is any difference in the experience whether I see it in the morning or afternoon. I suspect going as early as possible in the morning will avoid crowds, but I wonder if there is anything missed by going early (photography lighting, available services, Gaudi Museum, etc). Also, it looks like our day to visit will be Sunday although if I get feedback that afternoon is best and weekend crowds are a problem, we might be able to go Monday afternoon. Thanks!
