This was terrible and basically theft. We paid over $700 (family of 4) for this tour, after our original tour was canceled. It was clear that the "tour guide" we received was a last minute inept hire to be able to sell a last-minute tour. She knew nothing about the Colosseum, most of the time of the tour was spent in line, or the walkways or the line for the restroom, which she required. Very little time viewing the actual arena area. Thankfully, we left the "tour" a bit to actually go into the arena for family photos or else that opportunity would have been missed. No discussion of history or architecture in a location filled with interesting history and architecture. 20+ years ago this was my favorite location in Rome due to the interesting history filled tour. Going by ourselves would have been more productive - and about $600+ cheaper. It was a true disgrace and a theft of tourist dollars. The entire group asked her for more time in the colosseum viewing area and she refused - then had us wait 20 minutes back outside before she could lead us (she was our tickets) to the forum. We were literally held hostage on this tour, the smart ones got their photos against her protests for leaving the group.
