Overall this was an excellent experience. Arriving by ship our directions on the voucher as to how to find the starting point were a bit sketchy and the route on foot from the ship to the correct terminal building was poorly defined. That said, once we met our guide things improved immensely. She was knowledgeable and articulate. The ride to the upper elevation photo op was a nice touch to start...marvelous views of the old fort and monastery as well as the harbor. Moving on to the old walled city we saw many marvelous sites, enjoyed the native market for nuts and scents, the fresh gelato readily available was as good as we had all through Europe. We did not walk the top of the old city wall due to mobility issues and stairs, but those who did said it was worth the climb. We found the whole experience of the old city very charming and totally worth the time to visit...a place we would return to...hard to believe it was a war zone just 20 years ago.
Emphasis here has to be on "skip the line". What a treat to walk by the thousand plus people queque and enter with our guide and small group of 20 - 25. There were some stairs to climb, but you couldn't appreciate the granduer of this magnificent structure without making the climb. Our guide was very informative and happily answered questions from all of us. Time in the Colosseo was adequate and then the walk to Constantine's Arch, the Forum and the hike up Palatine Hill to the top were added features. The ease of the walk is definitely influenced by the weather...on our 97 degree day it was taxing, but everyone took it gradually and we only had one drop out from the exertion. This was one of the highlights of our time in Rome and well worth the money. Viator had there house in order. If there was any critique it would be the little wireless receivers tended to fade in an out and the earplugs were tough to keep in place...only reason we didn't give it 5 stars.
