You’d have to use powered coasters tho, relying on gravity assist to add speed for the drops would result in a pretty slow coaster, no rush of air in your hair unless you build a hab big enough for the whole thing. On the plus side you probably don’t have to worry about people falling from height, on the down side most coasters probably go past escape velocity so you’d have to be careful not to launch your tourists into space (or have a rescue vehicle on stand by or something)

Edit; How fucking cool would that Defunctland episode be though?

Escape velocity of the moon is 2.38 km/s (5300 mph), so I don't think that'd be a problem. Although you could probably fling riders pretty far at roller coaster speeds.
