Thanks, both of you.
I'm now considering reversing the order of our last two stops in Portugal, in order to give us a shorter drive on the morning of departure.
That would have us leaving Evora and driving to Coimbra for two nights, and then back to Nazare for two nights. Originally we had planned to travel in the order that the guidebook recommends, which would have had us drive to Nazare from Evora, and then on to Coimbra, with the longer drive back.
If anyone has a comment on this new plan, I'd be grateful.
