Thanks for the responses.
I’m at the beginning of my research. So far, we’ve narrowed it down to definitely NOT Oahu. One DDs MIL lives there and would be insulted if they came and did not stay with her. That DD mentioned the Big Island.
I haven’t researched areas of the island and I’m not sure we couldn’t choose a different NOT Oahu island.
I’ll do a bit more research and come back for more advice.
