You could also possibly exit the park, and find a quiet spot by the water. There used to be benches there. I'm not sure if they are still there. Not 100% sure if the benches are still there. Anyone who exits the park can re-enter on the same day.
If that are is not quiet enough, there are some very nice quiet spots if you walk a little further on the path towards the Boardwalk. (Just around past where the Skyliner is). Or for that matter, you could also take a short trip on the Skyliner over the CBR. It's a pretty short round trip.
Inside the park, first aid comes to mind.
In the morning, you can duck in by the bathroom area of Brown Derby, and there is a quiet area there to the left of the reception area. I am saying by the bathroom, but you have to walk a bit to get the bathroom. That whole part of the building is pretty quiet, and it is pretty. I think during lunch/dinner it gets busier, but in the morning, it is empty. I took some nice photos in there.
