Ever since the wording changed to "official business", my biggest question was whether GH Kauai would enforce by asking for travel orders. Rate still sits at $325 for the night for a base room, vs $850+ for public rates.

Checked in the other day. Proactively offered Government ID. They asked purpose for my stay... which I said was part vacation, part business. No further follow up and no ask for papers.
Combined with Globalist status (so no resort fee) and the new Amex offer for $150 off $700 at Hawaii Hyatts (wife and I both had the offer)... total for the room only with taxes and fees was $308.37/night.

Not to mention I applied a SUA for a standard suite.

Win!
