I wouldn`t realistically expect the transfer bus to be any quicker , waiting for everyone to get through customs/baggage collection then like I say, it can meander through the resort and depending on where you are staying it can take a while. Anyway, another point I would like to mention, I was once in the queue at Cicar in town behind a guy who wanted to extend his hire period. No dice, "iss no posseebler, you muss go back to the airport for theese!" anyhoo, Cicar have moved operations out onto the car park, speeds things up a bit. A plus point about the transfer bus is you can have a nice drink on the plane. I used to love a G&T !
