We are looking at doing Rome on our own (Med. Cruise, May 26). After looking over the excursions (and the cost). We want to "see" as much as possible without spending a lot of time at any one place. I have looked at this Gray line. They do transfers from the port and have a "hop-on, hop-off" bus tour of the city. Prices seem great ($240 for tranfers - 5 people in a minivan and $22.00 for a 48 hour bus pass). Plus they offer a 10% discount to AAA members. Has anyone else looked at this, or used this company before?
