We used both the arrival and departure services on our December trip. When we arrived we got through immigration and customs in about 15 minutes. They also call your driver and escort you to the curb and stay with you till you are loaded and ready to roll. On departure the time through immigration and customs was about the same and then they escort you to club MoBay with its free wifi, snacks, drinks and comfy chairs. There was no pressure to tip but we did anyway. Whether it is worth it or not depends on your budget and patience but if we can we will definitely do it again. Travel days, no matter how good, generally suck so the little bit of pampering was welcome and on departure the lounge was a huge improvement over the hard plastic seats, noise and overpriced snacks of waiting at the gate.
