That Family Travel Magazine
Adventures by Disney Portugal Trip Report was actually written by another guest on the trip - not by me - sorry for any confusion!
1) We flew to London Heathrow from the Faro airport in the Algarve so can't answer your question about the car service, but I'm sure you could email the Tivoli Carvoeiro Algarve Resort at
carvoeiro@tivoli-hotels.com and they could give you recommendations and estimates for the cost of a car service.
2) Air conditioning was great at the three hotels from what I can remember!
