We were two of a handful of people in GF at 6:30am on Saturday, and it was so quiet it was almost surreal. The downside of that though was that the items on the buffet weren't being eaten quickly enough not to dry out under the heat lamps. The hash browns seemed to have suffered in particular.
That said, the food was still good enough and a huge step up from the "you can have anything as long as it's 90% carbs" approach of GC
