I have a stay booked next month at the Hilton Bentley (On the Resort web site list)
I stayed there last fall, so I checked my saved copy of my Hilton Citi statement, and they charged my card as HILTON HOTELS. It did not include the word RESORT in the name.
I'm not sure if your issue was was due to the pre-paid rate, or does the hotel charge actually need to have the word RESORT in the charge?
Any other data points for people that did have the credit post? (Resort being in the charge)
