Are they worth it? Any particular site I should buy them from? I feel like when I go to most official sites they don't offer a skip the line option. I do not want to spend a lot of time in line and I don't mind spending a little extra if needed. I just wasn't sure what to expect and if I should buy them. I listed below the sites I am looking into. The one I was most concerned about was Duomo Milan. On their offical site they have lift tickets to the roof for the 5:30-6:00 time slot. Are they pretty good at getting you in during that 30 minute window? Especially if they close at 7, I don't want to get there at 5:30 and not get up there until 6:30 because of wait time. Thanks for all your help!
