Hi everyone!
Wow! Already in just a few hours I have received the helpful suggestion that we don't need to be met with a guide at the airport and that there are flat rate taxi's to historic Rome.
We have made several trips to Paris using the flat rate taxi system there -- and we found this to be a great way to go on arrival as opposed to taking the train when just arriving from a long airplane flight.
Also it was pointed out that we had better take more time to get over jet lag -- so I think we will plan to spend at least three nights.
We are not traveling with bicycles (we will be renting bikes later in the Pisa area) -- and hope to have very light luggage.
Now we have to research Rome -- especially by the RS guide book and by listening to RS Audio Europe.
Hopefully I can figure out how to search recent posts here for recommended hotels in Rome -- but if anyone is eager to share a recent great hotel experience, please do write! Thanks everyone!
