We are planning our first trip to Europe with the family (two teenagers) and have two definite stops we have arranged through home exchange in Gstadt, germany on Lake Cheimsee and La Spezia in Cinque Terra area. We fly in and out of Frankfurt and we have 17 nights total in Europe with a rental car.
Our current plan is to stay one night in Rothenburg on our first night in Germany, tour the town(yes quickly) and then head down to Lake Cheimsee for 4 nights. We then plan to drive through Austria to Northern Italy and stay 2 nights in the Dolomite/Verona/Lake Garda area which we are still trying to narrow down. We then head south to the Cinque Terre to stay 5 nights and take day trips to Florence and some small Tuscan towns. From there our trip is less defined as we need to make it back up to Frankfurt in 4 nights.
I am aware that we are cramming a lot in so I am looking for some input as to whether we should go the quickest route back or if we have time to stay 2 nights in the less quick route through Chamonix/Mt. Blanc area. Helpful kind advice is appreciated. Thank you!
