@misticjeff @Konni, @hank_2021 Looking for tips since we have not ventured out in Porto anywhere as much as Lisbon. Our friends will have all of this Sunday in Porto. They are staying at the Hilton Porto Gaia like we did. I have sent them our https://www.youtube.com/@JonesTravelers/playlists so they have seen our Porto playlist which we took when we stayed at the Hilton Porto Gaia.
Lisbon forecast for Friday is sunny for their Lisbon itinerary one-day-in-lisbon-itinerary, but the Porto forecast for Sunday is looking like a chance of rain.
Any advice you can offer would be appreciated. I have sent them the link to https://www.youtube.com/@OhMyPortugal/playlists
