I will be visiting Italy for the first time this October and am trying to determine which Colosseum tour I should pick. There are several options, all with different durations and prices. When you went, did you just buy entry tickets via the Co-Op Culture website? Did you visit the Arena and/or Underground, and if so, did you think it was worth it? Or, did you purchase a tour via a third party like TripAdvisor or GetYourGuide? Did you go without a guide, and if so, did you wish you had one?
Let me know what you would recommend!
