Need help trying to find the best economical way to transport my daughter and her family (husband plus a 2 year old baby) from Geneva airport to La Conversion, Lausanne.  Train is not an option as they will have a long flight with a baby and would like to travel in a car.  Hope someone can suggest what would be the best way.  I have tried Uber but they are no offering baby seats this year. 

Any comments/suggestions would be greatly appreciated.

Thanks.
