Apologies for a semi-repeat but my question is a little different than last time re: the above subject.
I have a car reserved out of Frankfurt Airport, dropping it in Nuremberg Airport, with Budget via Travelocity. I have tried to find out if the car can be taken across the border to Switzerland AND if I can stick a Swiss motorway vignette on the windshield but to no avail. Travelocity hasn't been helpful and calling the Budget desk in Frankfurt, an international call, was problematic. I have some level of confidence that worst case they will tell me at the rental desk that Budget will ask me to pay a surcharge take the car across the border, and that's fine, but I was trying to square this away before the trip.
In parallel, I am starting to look at alternative rental car companies and am seeing conflicting reviews on the web re: Sixt. In some cases it's rated highly; however, I've also seen lots of recent reviews that are scathing.
Ignoring price, I was wondering what companies people have rented from within the past year with few or no issues and as such you would recommend. Thank you.
