I can only pick one pair for my brief stop in Tuscany. This will be my first trip to the area, so which pair is more critical to see on a first visit?
Currently, I am leaning toward Florence and Pisa, but missing Siena on this trip is really bothering me for some reason. I thought I might do an alternative to Siena by going to Orvieto and Civita di Bagnoregio as a day trip from Rome, but...how can you replace Siena or its Piazza del Campo? It's very frustrating...
If anyone has an opinion on this issue, I would appreciate any advice. Thanks.
