Finally I get to be that guy in the comments with a weird about of relevant experience. I built the world's largest hamster wheel in 2012[1], a large rotating circular platform ~6m in diameter.

It was a fun and unique experience to run on for a short amount of time, but most people would get dizzy after a few minutes of jogging on it. The curved platform also turned out to be a bit of a tripping hazard. It was more often used as a sort of swing (could this work on the moon?).

I'm skeptical that the experience on the moon will be much better, especially since the diameter they're proposing is even smaller.

With a hamster wheel, aren't you basically running in one spot near the bottom? If so, do you know what causes the dizziness?

Because you're looking forward at the platform that's moving down and toward you. Kind of like if you were to stare down at the belt of a treadmill while it's moving - it would be disorienting after a while.

If this dizziness is anything like VR sickness, you can become acclimated to it.

And you might actually just wear VR (or augmented reality, AR) goggles to counteract it.
