I thing some children of minor gods whose parents are major gods could stay in their grandparents's Cabin.
Like Kymopoleia or Triton having demigods? Poseidon would want them in his Cabin.
Aristeu, the god of beekeeping? Son of Apollo, sure his kid would be here.
Still claimed by their actual parent, just in theri grandparent's Cabin with their uncles and aunts.
Not sure if like...Hebe's would be accepted hin Zeus's?
