Chose this cruise for its cruise destinations, size of the ship which is not overcrowded. The delicious cuisine on board and at local stops. Excellent wines from local vineyards. The comfort of the cabins on board were excellent. Great entertainment nightly. Excursions were fantastic with free time. All bus transportation was second to none, drivers very professional. Our cruise director Patricia made our whole experience the best. What a wonder she was. She was our tour guide on all of our excursions. We chose for the extension before the cruise started in Lisbon which we toured on our own. when we arrived in Porto we handled by Patrica who was Vikings Cruise Director. She gave us a wonderful tour of Porto which she is a native and gave us a lot of information and a lot of great places to visit. Through the whole cruise she always had a smile on every tour and would also participate in activities on and off the ship. At night she would MC the nights entertainment, which was always fun.At the end of the cruise she was also stationed at the airport to make sure everything went smoothly. All of this has made this a wonderful cruise that you will cherish for a life time.
