Forgive my ignorance, but I live in an area of the US with a poor public transit. We will have 5 traveling to Italy. Are there cabs that fit 5 people (relatively adult-sized....it will be two adults and 3 teen-ish)? Is there a particular service we should be aware of when in Rome? I did find this link, but it did not address size of cabs.
These are the questions you ask when you grow up in the Appalachian mountains ;-)
