I have a work trip to Spain and wanted to spend a week in Portugal afterwards as I am already in Europe.  I arrive in Lisbon from Madrid on Saturday morning Dec 16th and will fly back from Lisbon (to the US) on Friday Dec 22 in the afternoon.  I am pretty open to seeing whatever I can see in the country in 6/7 days but would like to spend at least a couple days in Lisbon.  Looking to find a travel companion as my friends just cancelled on me based on a family situation.
