Hello everyone. I'm hoping someone can help me confirm which andante card I should purchase for a week in Porto. I'll be arriving at the airport outside town and staying near the historic center, but I'll be traveling all over, from Gaia to Vila do Conde throughout the week. Am I correct in saying the 72 hour card will allow me to go wherever I'd like by metro without worrying about zones? I'm assuming I can purchase a card at the airport, right? From what I've read, I'll need to purchase a new card after 72 hours since it's not able to be refilled.
It looks like I could also use this card for the bus as well, but the more I tried to find a clear map or information on the bus routes, the more frustrated I got, so I'll probably stick to walking and the metro this trip and maybe tackle figuring out the bus system next time I visit. The last time I was in Porto, it was only for a few days and I didn't wander far often, so just walked or used bolt.
Thank you for any help you can offer!
