I am thinking with a family of four (two teenage boys) that VRBO might be the way to go rather than two hotel rooms? I think Lisbon and Port (4-5 nights each) VRBO is best but I am SUPER open to different ideas and suggestions! Renting car and stopping at Obidos, Coimbra and Tomar on the way from Lisbon to Porto. I have searched relentless online....
Thank you!
