Yes, several times. Timely, dependable and pleasant folks, start to finish.
A friend with more mobility issues than I regularly used the full range of options: met when getting off the plane, golf cart to immigration, VIP line through immigration, luggage pick up at the carousel, taken directly out to where the limo was waiting and delivered to the front door of his hotel. It made the trip possible for him. Because you're brought through the Diplomatic lanes at Immigration they DO request no tank tops, flip flops or "other wear that might be deemed inappropriate by the officers".
Around $55USD if you also book a limo (at an additional cost), a little more if you want to get your own taxi.
