Planning help: I did a lot of research and kept coming back mostly to: MyPortugalHoliday.com . There really weren't as many helpful YouTube videos or other sources as there were for Iceland last year.

Lessons Learned (What I would do differently): As usual, more time, especially on our road trip between the big cities. We didn't realize that the day we were taking a train from Porto to Lisbon was a holiday so tickets were sold out until the afternoon. Book early! Restaurants in Ribeira in Porto fill up for dinner - make a reservation.

What were your favorite things?: Porto was storybook Portugal. We chose to stay in the most touristy part of town, Ribiera, overlooking the river so it was crowded and hard to find a table at a restaurant. But it was stunning. 

How much did it cost?:  

Airfare: $695 x2 (TAP Air Portugal), Washington Dulles - Lisbon 

Transportation: $537: 2 day Rental Car - Seat Ibiza  from Budget @ $254 + CDW and Toll Transponder @ $49 +  one way fee to pick up in Lisbon and drop off in Porto @ $104 + Gas @ $54 = 278 miles or 7.4 gallons of gas @ $7.19/gallon.
