I have asked several questions on trip advisor regarding our trip to Portugal in September, 2014. I was getting my itinerary somewhat set pending approval of the other 3 people. Now....the other man in our group has been to the doctor. His walking ability is significantly decreased due to poor circulation. This has worsened in the last 4 months. I'm back to square one with planning. We have 14 days in Portugal. We land in Lisbon. We planned to take the train to the algarve. I have been looking at algarve forums. Does it make sense to visit this area if we can't walk the beaches? What are some other options for tourists? We thought then we would find a cheap flight to Porto and tour the Douro Valley area for 5 days. Perhaps a river cruise. Then we were going to take the train to Lisbon and spend the remainder of our time stationed in Lisbon but touring the area. Now with this situation, does this itinerary make sense? Can anyone suggest ways to tour with someone who can't walk long distances? We have talked about taking a portable wheelchair with us. This person doesn't want to spoil our trip but his circulation problem is setting limits. I'd appreciate any help you can offer. Thanks.
