I am flying to Lisboa from Washington DC, USA on Thursday and arriving at Lisbon on Friday at 6 am. I have a luxurious Airbnb booked for ~$60 for two nights and three days total (cheap!) at city downtown. It can accommodate 2-3 people max. We will explore the city on Friday, Saturday and Sunday. For Monday-Saturday, we have two options:1) Fly to Azores islands for $150 round trip    - We will arrive at Pico island.  -  I would like to do a day hike and see the summit of Mt. Pico; highest mountain in Portugal   - We can stay in Pico for 2 days and then we take the ferry to Sao Miguel and stay there for 3-4 nights - In Sao Miguel island, we can do a scuba dive or snorkeling for $50 and see the rest of the island. We may need to rent a car for two three days.2) Rent a car for $150-250 and travel Portugal or/and Spain - Still planning
