We were on a package tour in 2008. 3 nights in Rome, 3 nights on the Amalfi (Maiori), 2 nights each in Florence and Venice. We fell in love with Italy.
We are looking to return to Italy either in 2010 or 2011. 3-4 nights in Rome is mandatory. We are considering the following for 4 nights:
1) Siena
2) Cortina d'Ampezzo (Dolomite region)
3) Portofino
We would navigate Rome using public transportation. My question surrounds my other three options above. Are these destinations possible via trains or other public transportation? I really don't want to rent a car and I also don't want to take another packaged land tour.
Lastly, If I get to these locations, how best to see the sights without a car rental.
Any suggestions are welcomed. Thank you.
