I was sold on the clubs many years ago (more than 20) when I was at O'Hare one night when the airport was unexpectedly closed because of weather. I happened to be in the RCC at the time, waiting for my flight. I was called to the desk, given a reservation at the airport hotel and booking on the first flight out (another airline) the next morning, with a chit for dinner and a toilet kit. When I left the club for the hotel (by way of baggage claim, where I picked up my toilet kit), I passed through the airport waiting areas, where no one yet knew the airport was closed. I got to the hotel and checked in with no sweat. Went to my room, then came down for my free dinner. By then, the lobby was a zoo. You better believe my club membership paid off. I immediately bought lifetime memberships in every club that provides free drinks, and I've had several similar experiences since.
