Since Jewel only has a tiny cafe and not a Sorrento's/Cafe Prominade, it's no surprise you can't get pizza until after 9pm. Just comes with the territory for a smaller ship.
I've never seen this.
What I usually see is 3 elevators within 2 floors of where I am, but it's the elevator 5+ floors from where I am that ends up coming to me.
So answers for the first two don't matter. Answer #3 accurately (especially in light of someone lying about it then giving birth on a cruise).
Always answer "no" to #4.
