If you have seats for the kids on the plane definetly take your car seat for the plane. They know their seat and feel secure in a strange environment plus its safer if there is turbulence. Then just pop them in the rental when you get there. Take a stroller with you to the gate at the airport to help you carry the car seats (I had two car seats the last trip and this worked great). Then the attendants stow the stroller right under as you are boarding. makes a great luggage/car seat carrying cart!! The only downside is security -- you got to put all the seats and stoller/s up on the conveyor belt to be x-rayed. This can be a pain but thats the way it is today!
