I booked the "secret Rome" vespa tour via the Viator website. My husband was a bit sceptical at first thinking that we were going to be on the back of Vespa's with some young male "hoon" drivers and that we were probably going to be taking a chance with our life jumping on the back of a Vespa with someone we didn't know. He was wrong. We were traveling with friends and when the four of us walked out of our hotel we were pleased to see 4 drivers who were older than our sons. They were nice blokes, very careful drivers who made an effort to calm our initial nerves. By the first stop we were all happy that we had taken a chance on this tour. It is an exhilarating experience and the closest that I could feel to being a local. We traveled along main roads, back roads and little alleys. The tour was great and before we started the guys checked with us what we had already done so that they did not double up on anything. We went to see things that are not readily accessable to most tourists and we all came away feeling that we had learnt a little more about Rome and that we had seen and experienced a more authentic Rome than most tourists. This was the highlight of our stay in Rome and I can not express in words to you how much you should step out of your comfort zone and just book this tour. Make sure you book the secret Rome tour - the duration was about 4 hours.
