|Subject: VISIT TO PORTUGAL|
your trip plan in Portugal is interesting but it is very long. The road are quite narrow and there are a lot of TIR on the road then traffic is slow. In particular the trip from Porto is very ambitious, I am afraid you'll spend many hour driving and very less time visiting. I suggest you to get the highway when it is possible. ....Yes, I now that driving on highway is not beautiful but you can save time for visit. I visited Portugal 2 years ago and major problem was to drive quickly!
About accommodation, I found a good rate quality-price in the Ibis hotels.
Have a good trip. Marco in Milan (Italy).
