It's gonna weird to ask i think, but i gotta say, another area for the gold saucer, at the roof.
What i mean is an open air roof with maybe benches and stuff like that where you can look at the sky and just sit there, take screenshots and stay idle, resting a bit.
Like every Casinos the Gold saucer is quite claustrophobic, with the absence of windows and such, but the difference here is that this casino belongs to the final fantasy universe, so to me at least, it would make sense to have this kind of open space in the exterior where you would be on top of the building and being able to watch around, whenever it is day or night and in a place away from the constant "noise and chaos" of the main casino.
Maybe it's completely useless, and it is possible it is, but to me it just seem like a nice addition.
