Spain and Portugal by train in two weeks.

How about Barcelona – San Sebastian - Rioja - Leon – Santiago – Porto – Sintra - Lisbon? We rented a car for a section in Northern Spain to hit the wineries, but it can be done by train. See pictures and details at my personal blog at:http://gadtravel.blogspot.com/

Last April we did just Spain in two weeks and we were on the go every day. Every day was full, yet at a leisurely pace. We did four nights in Madrid with side trips on two days to Toledo and El Escorial. Two nights in Granada, two in Tarifa (one day to Tangier, Morocco), three nights in Rhonda (with two side trips), two nights in Sevilla and last night back in Madrid. All of our travel was by either train or bus. Hope this helps at least with Spain.
