The scenario...you want to book the cheap flight to Jamaica with the 10hr layover in Miami. It only makes sense to leave the airport and check in to a hotel. The issue is you land at 8 am and don't want to spend full price on a room. So you get a "Marriot Bonvoy's Day Pass''. The day pass will give you access to great perks, access to a room at a pocket-friendly rate.
