Welcome the Liberty thread Brenda!! Delighted that you're joining in.
I've been to Florence several times, and it's one of my favorite cities in the world! Really nothing like it anywhere, and I loved it even more than Venice or Rome. I know time to make that visit is short, but if you do go, you'll love it.
Have been to Rome before too, but never really had time to explore the city alot on our own. This time we'll have three days to get to know the city a bit.
btw Barcelona is also on my favorite cities list. One of the things that made this itinerary so appealing.
