I need to book tickets for Sagrada Familia for the final week in October. They're sold out on the official website, and all that's available are third party resellers. Are there any that are legit? Does anyone have experience with buying them from someplace not official? I am fully prepared to lose money on this, but my mom really wants to go in as a birthday present, so I don't want to end up scammed with no ticket. Thanks!
