I cannot recommend this tour enough! The instructions to find our tour guide were clear and we found her without problems. She explained clearly the layout of the day and guided us around to the back of the Colosseum to skip the line. We only waited 5 minutes to gain entrance through security. The archeologist we were assigned was fabulous - very knowledgeable and allowed time for photos and questions. There were only about 12 in our Colosseum underground tour group. The view from the highest level of Colosseum was phenomenal and the lowest, underground level gave an interesting perspective to the Colosseum. There were 30 minutes at the end of our tour with underground to explore Colosseum by ourselves before meeting again outside. Our tour of the Roman Forum
was also amazing. He gave a unique slant to the history of the Roman empire and made it really fun. There were only 4 of us with Tom. When Tom finished we were then free to explore the Forum and Palatine Hill at our leisure.
