I believe it is 50 going in and 30 departing. We have only done the depart. Carol is right the food and drinks are worth it with a comfortable lounge, table service and decent food buffets. The bathrooms are very well kept and there is showers and room to change if you leave the beach and head to airport. Most resorts get you to the airport a couple hours or more before your flight so if you are the eating and drinking type it pays for itself. Gets you through departure security quickly too.
If you are flying Southwest ( I know Carol won't be) the gates are at the other end of the terminal so leave the lounge 45 minutes before your flight time. They are pretty prompt about starting the boarding 30 minutes ahead.
We have neve been through the arrival with them. Most we ever waited was an hour. Our resort has their own lounge so we go there and wait on transport.
