Just tried BRG on this property.

Hilton replied within 24 hours (yay) and said no (boo).

"I have reviewed your reservation and compared it to the rate published on Virginholidays.com. I was unable to approve your claim because it did not meet the criteria to qualify for the Price Match Guarantee. Unfortunately, we were unable to find a lower rate on the third party site with the same booking (payment, cancellation). Additionally, the third party site does not have the ability to change their offer to the local currency available on our Hilton.com website. The terms of our Price Match Guarantee program specify that “The same accommodations must be available for booking at a qualifying lower price in the currency of the hotel when we validate your claim.” (please see “Reviewing your claim” at PMG Overview & Terms for more information). This requirement is in place to avoid any inconsistencies when using outside currency converters."

So I can book via VirginHolidays for two nights for ~$125 US – the price has now gone up since I wrote them, so checking on a Best Rate Guarantee has cost me money already instead of just booking! – but that's still cheaper than Hilton.com's $260.77 US.

To say they can't match a rate on a legit website just because Virgin doesn't have a currency converter... Hmmmhm.

Sigh. Resort fees are a drag. I made a point to stay here when the hotel first opened, and have stayed a few times since. Nice place, but $45 a night for water and "free phone calls" is a total turd move.
