To Tauck or not to Tauck???Traveling with college age children in France and Italy during the Christmas holiday. We've never been to either and think a bit of structure might be necessary in that we'll be traveling for 12-14 days. Have been encouraged to use a tour group (Tauck suggested) but worry that it will be a senior crowd (I'm almost there and would welcome that) and too "tour-guidey" for our younger travelers. We love independence but believe that some tours might be beneficial. What is the best balance? Any suggestions appreciated!
