Thank you ALL for valuable input .

This is my first trip in Switzerland. And we plan to drive within Switzerland.

Is it easy to find a parking in city . We plan to visit Geneva area, interlaken, Grindewalt

Do you recommended to bring a portable GPS from home or should I rent a car with it included

Do you recall how long it takes to take the shuttle from Geneva airport to car rental parking?

When you return a rental car, do you return at parking area or at airport. Is there any gas station close to airport to refill gasoline before return the car rental

Please advise
