Uber!
Parking is limited, for guests not staying on site, we recommend you Uber or carpool.
If you have time to explore before and/or after the wedding we recommend you try to make your way down to Algarve, in southern Portugal. There you will find amazing beaches, food and nightlife. Algarve is ~345 miles south of Porto and ~170 miles south of Lisbon. There are trains from both Porto and Lisbon to the Algarve.
