I don't think you should expect to pay nearly that much. Hawaii is expensive and always will be, but not $800/night expensive unless you're at the Four Seasons or Fairmont.
Anecdotal but we stayed at Hotel Wailea in summer of 2017 for about $450/night. It was a 15th anniversary trip and a known splurge, but we could have gotten much less expensive lodging without even trying very hard.
