Overall a very pleasant and educational cruise and excursions. The valleys along the river and interior were so perfectly structured and beautiful with vineyards, olive trees and other trees and cliff side homes.
My only critique would be that it would have been nicer to have a bit more free time in the areas we visited as sometimes we felt a bit rushed to get back to the bus "on time"...
The last excursion for which we paid $139 each, we spent around 2 plus hours on the bus (in traffic due to an accident and rush hour) and only got to enjoy the the outside of the historical buildings and because of the traffic and restroom delays we only spent about 2 hours in that part of historic Guimeraes... so that was unfortunately disappointing.
One highlight was the visit to an authentic "bakery" where we sampled wine, and pastries for about 30 minutes... then we had 20 minutes of free time... just not enough time!
