It's interesting to see the Virgin Hotels site pricing is so much cheaper than Hilton - I've just been looking at a 4 day stay in Oct and they're USD829.95 for 4 days incl tax and resort fee vs USD970.76 on the Hilton site with both being the same room and refundable rates.
Anybody know if Hilton offer BRG against the Amex travel booking site? They're significantly cheaper than even the Virgin Hotels site.
