I'm not sure if I should if I should start a new thread, but I'll post here for the time being since it relates to this topic. My friends and I are discussing a trip to Spain next summer that includes Madrid and the Basque Country. We are discussing options of renting a car to drive from Madrid to the north (probably San Sebastian) and then around the Basque Country. A few pros and cons:

CONS
1. We will be a larger group, anywhere from five to eight people so we would need a larger vehicle to hold all of us and our accompanying luggage.
2. This larger vehicle could potentially be quite expensive.
3. I've heard that parking in San Sebastian is quite difficult.

PROS
1. A rental car gives us a lot more flexibility for visiting more places, especially those that are off the beaten path.
2. Renting a car might be easier than making reservations for a larger group for several public transportation journeys.

Any comments about driving versus public transportation in the Basque Country are appreciated!
