Agree with Bob. As it is you will spend a lot of precious time in transit just to get to cinque Terr

My boyfriend and I are going to Italy for 11 days. We are planning on doing 2 days in Rome and 1 day in Venice but are not sure about which other places to choose. We do not like resorts, museums, tours, and city life (Rome is the only exception). We love the water (Coastal areas), wine, food and beautiful views. Below are a few options that I've been reading up on. Which is the most beautiful and the the one we would enjoy the most? Do we have time to do 2?
If you only have 11 days, does this include arrival and departure days? If so, your time on the ground is quite short so you need to limit your travelling between places to a minimum so that you don't waste it.
Two days in Rome isn't enough and one in Venice is a waste of the travelling time. You need IMHO at least 3 nights in each place to do them justice. This doesn't give you time to see much else, so I'd recommend flying into Rome, 3 nights in the Lakes and then Venice, from where you'd fly home.
Off hand I'd say the Amalfi may be one of the best options given your preferences - so so much to see and do there - not only the Amalfi but Pompeii, Capri, Ischia, Paestum, ascending car rental paris thrifty Mt Vesuvius to the crater
You certainly have time for one other place and each of your options could be great for your tastes - the Cinque Terre is neat but sadly overrun with tourists in summer, negating the normal car rental paris thrifty romantic car rental paris thrifty atmosphere but if going outside of the summer rush it can be so neat.
Agree with Bob. As it is you will spend a lot of precious time in transit just to get to cinque Terre. I would pick two locations nod drop that myself and enjoy the time in rome and Venice rather than in more transit given your short time frame.
