We are planning a trip in early September (9/4 - 9/16) and trying to decide on a locale. Ideally we would divide time between 2 or maybe 3 areas with the possibility of day trips. All ground travel would be by train (we love train travel). We are relaxed travelers, big walkers and like a mix of sights (art/architecture) and great food. Not big beach people. We will also be celebrating a 50th birthday during the trip.
Initially I thought of Venice/Florence/Rome - but due to crowds and cost, I think we would prefer to do that trip in the Spring.
Current front runners are Granada/Seville/Madrid or Lisbon/Sintra/Porto. We have been to Madrid/Barcelona and loved it, DH has been to Seville many years ago and would love to go back. We have never been to Portugal and have heard a lot of great things, but mostly from beachier friends. Any preferences - or alternative suggestions? Will things be closed that early in September?
