We stayed in the concierge in Nov. 05 and really enjoyed it. We mostly took advantage of the snacks/food. We're not too crazy about the dining at DL, so we were able to get a nice breakfast, take some bottled water, a snack at lunch, and some treats in the evening. Everytime we walked through we were grabbing a drink/snack, which really saved us money in the parks.
One tip, the soft drinks are in breakable bottles and you aren't allowed to bring them into the park, so you'll want to bring a mug to pour them into or ask for a styrofoam cup.
