I could swing either way on this one. I think it being more exclusive would be cool, but even right now, it’s just a little awkward to get to (Even with a jet pack you’re likely to bump your head), and I often don’t have a jet pack equipped.
In the end, I think it can be exclusive without the jet pack usage, maybe just have the staircase tucked away, or have it behind a door that doesn’t open until you try to open it a few times, or a number of other fun ways to make it a bit more secretive.
(Also this makes me think of potentially having a second “high roller” level to the Casino full of machines and tables with higher bets/payouts)
