Go through those doors and take the tram to D terminal, go up the long escalators then double back to the left (the club looks back over the escalators, sort of).

Per nsx, The Club at MCO is accessible to Southwest passengers by riding the other train to gate 90. You can cut across on the air side of security between that train and the train that connects to Southwest's gates. nsx also mentioned that the Club at MCO is a very, very nice lounge and is the best US domestic terminal lounge he has ever visited. shammers and northsider agreed that the Club at MCO is a nice domestic lounge with decent food and alcohol.
