You are picked up and/or dropped off at the dock in Civitavecchia.
Your drive takes you to, in and around Rome. Time management by your guide affords you the opportunity to view many sights in a short time including St. Peter's, the Sistine Chapel, Coliseum, Forum, Trevi Fountain, Circus Maximus, Spanish Steps and Piazza Venezia. Your guide puts it all in perspective from the top of the Gianiculum Hill while honoring your additional requests when possible.
You cover a lot of ground in a short time because the attractions are in close proximity to each other. The team of driver and personal guide know how to efficiently route you to and through them.

When this tour ends, you have a comprehensive understanding of The Eternal City and, perhaps, a list of sights requiring further exploration upon your inevitable return.
