I went by Thanksgiving Day and Black Friday. Again, no chips or granola bars. The first time, nobody else was there. The second time it was fairly crowded. I also went to the AmEx lounge on Friday, it was very crowded, but did have bottled water and bags of chips.
In the AP lounge, I was told the Cokes don't freeze well, but Sprite and Diet Coke do. Couldn't see buying a bottle when I had a refillable cup already... On Thursday I was given the AP buttons for September and November. On Friday, they only had the November buttons left (My daughter and wife had not picked up theirs yet).
Comparing the two, the AP Lounge is easier to locate, larger and more comfortable. The AmEx Lounge was smaller and way more crowded, It seemed to be the most crowded area of the park. Also, the AmEx lounge was much harder to locate. However, the AmEx lounge did have complimentary bottles of water, chips, and granola bars. We grabbed snacks, water and left, as it was uncomfortably crowded in there.
