As above, get an agent that had access to FHR, Virtuoso, Privè, FSPP, STARS, Luxury Circle etc etc
Often the rates are the same as BAR, however Privè upgrades are confirmed within 24 hours of booking which is a huge benefit.
FHR can be worth much more when theres’s an additional $100 or $200 USD credit. I had a stay at the Sofitel Darling Harbour where the $300USD credit was worth more than the rate I paid.
Mariott downgraded STARS last year.
You can check and reserve FHR and Virtuoso online with benefits clearly outlined.
