After posting, I checked your exact dates (instead of mine), sorry about that. The current offering looks like Mauna Lani to me, even though it says last person booked got the Fairmont. It is 95% recommended. That figure ought not to change in 5 minutes. The hotel I found was 100% just now. The regular rate of the one on your dates is $264, and the one on my dates listed as $292.
Further, if you check the comments guests have left on Hotel Condition, the one for your dates mentions updating recently. The one for my dates says needs updating, and describes a more generic resort. Also says:
Good hotel but needs updating ."
"gorgeous architecture and decor."
Fairmont Orchid was built as a Ritz Carlton and still has the Ritz marble, brass, and generally ritzy look, whereas Mauna Lani is often criticized for its cruise ship looking architecture, but has updated rooms whereas Fairmont does not. I think (spec) that you are seeing Mauna Lani, as thereyouare said above.
