1. I'm pretty sure that the Vaillancourt Fountain is still there in the year 3195. It's hard to tell because some palm trees are blocking it, but that looks like the East wall to me. It's directly below the Tulip statue.

   Proving that we are in the Terran Empire timeline, that means it will have lasted 1,169 years longer than it will in our universe.

2. Not only is the Hyatt still there, but the rotating restaurant at the top is lit up!

   But back here in the Terran timeline, while it has finally been repaired, it is now a private club.

3. Quark's still exists, so that's a pretty nice 830+ year run, too.

Previously, previously, previously, previously, previously, previously.
