Yes, cost is not not the only thing that will influence our decision, but I am going to attempt to do a cost comparison between Train and Rental Car for a 5 week trip this summer for 2 adults and 2 late teens: I'm curious to know what more experienced travelers would expect for a cost comparison. Some trip details:
Barcelona/Girona (6-7 days) to Nice (10 days) to Italian Lakes (3-4 days) to Swiss Alps (7 days) To Bavaria (4-5 days) to Paris (3 days).
At each of these locations we plan to do day trips (approximately 14 day trips total) that will be by train or the rental car.
We have a quote for a leased vehicle of $3,032.00 (rental only, this doesn't include fuel, parking, and tolls).
If there are any rail passes that we can explore we are open to suggestions!
