There was nothing in MVJ and when I called to ask, I was told nothing was available. There may be something offered once onboard but I'm looking at private tours and looking for people to join us. There are several that give you 7-8 hours (it's an hour each way) with drivebys of many spots and let you off at the Colloseum and the Vatican for more time there. Since these are priced by the vehicle, costs go down if we have 4 or 6 instead of 2. (nearly $400 each for two, $250 or more for 4, and about $200 for 6). Please let me know if you are interested--maybe we can join together?
