We are traveling to St. Anton via Zurich in February - we are 2 adults, two teens and lots of luggage + skis. I have a reservation for a rental car, but would we be better off booking a taxi/shuttle? Is a car useful to have while there? We would like to spend some time exporing Lech and Zuers as well. Our hotel has free parking and we are located right in town near the Galzig and Rendlbahn lifts. We had a rental car in Chamonix a few years ago and found it very useful, but I'm not sure that's the case here.
