Make sure you right click directly on the planet/moon with the rings with a constructor selected and choose the "Build at Planet/Moon xxx" option when you order the build. My resorts follow the planets around just fine.ORIGINAL: Hard Sarge
(build a resort at a interesting place, a ring planet is interesting, but, you can't build one at the planet, but you got to build it away from the planet, so, what, every 150 years, when the planet's Obit comes back around, you may get some people to show up ?)
Edit:
If there's already a resort base at the planet you can't build another one so the option won't appear. I'm guessing the same applies to asteroids but not sure about the black holes and neutron stars.
