Portugal September Itinerary Sanity Check

My husband and I are visiting Portugal for 2 weeks at the beginning of September. We have round trip flights NYC to Lisbon and plan to rent a car and do the first 7 nights in Carvoeiro, then fly from Faro to Porto and do 3 nights in Porto, and then train to Lisbon and do our last 3 nights in Lisbon before flying out.

I hate feeling rushed on vacation and was only going to have us do the last 6 nights in Lisbon but FOMO got the better of me and I booked a Ryan Air flight from Faro to Porto.

My question is does this sound like an okay itinerary?
