26/F traveling to Portugal 9/15-9/22

Hi Reddit! I'm going to be traveling to Portugal 9/15-9/22. Will be in Porto 9/15-9/18, lisbon 9/18-9/22 (flight departs at 5pm). Planning to do a day trip to Sintra while in Lisbon. I'll be doing a lot of full days (early mornings, late nights) since I don't have much time if you're ok with that. If you'll be in any of those cities in the time frame, send me a DM with your interests/itinerary and we can try to organize something!
