I thought it was pretty good, although we didn't use it all that much. We were staying in a garden suite, and it was quite a hike to the concierge lounge.

We did go up every day on our way to the parks for coffee and a quick bite to eat. This is what I saw while we were there: Mornings: various pastries, bagels, muffins, cold cereal, fresh fruit, coffee, milk, juices, ets. Mid-day: a couple of cold dips, chips crackers, gold fish, m&ms, maybe a veggie tray, drinks. Early evening: hot appetizer, veggie tray, pb&j sandwiches, cheeses, crackers, wine. Late evening: coffee, cordials, various desserts, cookies, etc.
The staff there was friendly and courteous, if not overly outgoing. They were helpful when we had questions; but didn't go out of their way with greetings and such when we entered the Inn Keepers Club.
Hope this helps some!
