Will be attempting my first camino this coming May. My flight is expected to arrive at 2.30pm on the 2nd of May (Saturday). Whats the best way to get to Porto Cathedral from the airport and any idea what time they close on Saturdays. Will need to get our camino passport before we start walking the next day. Hoping that there wont be delays in collecting our checked in luggages also. Anywhere else around Porto we can get the credential aside from the cathedral? Thanks!
