As mentioned, the Club Level rooms on the 6th floor with the lounge are only for DVC. But unless you are at the far end of one of the halls, it's an easy walk, then elevator to the lounge. We've had the opportunity to try a few of the club lounges at WDW, and AKL Club Level is without a doubt the one we like best - the staff, food/drink options, the lounge - all really nice and a very nice perk during your trip. So we'd say make the reservation, put in a request for a room near the lobby/entrance (the lounge overlooks the lobby), and enjoy the stay!
