Jamaica Club Mobay

Depends on several factors. Time of year, time of flight arrival, day of the week, etc... I’ve used it before, but usually when I’m arriving on a day of the week and at a time when a couple of other flights are arriving or have arrived shortly before I got there.
It has saved me time when I used it, but the amount varies. Their arrival (and departure) lounges are nice. I prefer the food and drinks in their lounge to the couples lounge for sure. Be sure to fill a tumbler full of rum punch for your ride from the airport to your resort.

We arrived around 1:15 and had we not done Club Mobay we would be still sitting in customs. Haha just kidding but it really would have taken us an hour or two just waiting in line. We sat in the lounge and had enough time for a rum punch x 2 while they went and got our transfer for us. I think it's worth it depending on your arrival time

Did it once. We were the only ones when we landed. Waste of money. Didn’t do it 5 other times and sat up to an hour.
