|Subject: Re: Portugal|
You will not want the car in Porto so we'd definitely recommend that you pick up your rental car either at the beginning or preferably at the end of your visit to Coimbra.
As discussed recently, whether or not you reserve ahead is a personal decision. Our preference is knowing in advance where we'll be staying and not spending our time seeking accommodations. But many people feel exactly the opposite, so we're not comfortable telling you what you should or shouldn't do.
Hope you fall in love with Portugal, as we did!
