Very quick to come when told was at point of pick up, not a very talkative driver until min or so from hotel.
Difficult to rate this particular experience - all of our dealings with the service supplier up to the point of requiring the service were good and the issue we had was caused not by the supplier but by the entry to USA taking over 2 hours due to IT issues and by the instructions on the voucher being incorrect - they told us to call the supplier once we had collected our bags from the carousel. By that time the supplier did not have any cars available and we had to find a taxi which actually was in practice easier and did not cost us any more that the voucher!
After we found driver and made contact I can't fault the service. Driver friendly and helpful and we made it easily to hotel - phew!
The number on the instruction page was incorrect and I spent a few times calling Carmel for assistance. This is a pain as international mobile.
Anyhow we got there in the end , shame a bit of time wasted till we got our car.
