Last year my wife and I and friends did a great tour with Odysseys Unlimited. The tour name was called Portrait of Italy from the Amalfi Coast to Venice, it's a 17 day tour. The tour group is limited to a max of 28 people. We had a great time. The hotels, food places we saw were great. Their web site is
