We're going to be in Portugal in late April/Early May and I'd love some help with a tentative itinerary that I have arranged. Here's what I have so far. Each line is a day, parentheses indicate where we're sleeping, and the question marks indicate an unplanned day (I'd love some thoughts on where to spend that day and where to go. I know Germanic Europe and Italy like the back of my hand, but I know zero about the Iberian peninsula. Portugal experts, help me out!!
