Merging HGV Reservation with a normal Hilton Reservation
I booked a HGV reservation for two nights in NYC to attend a timeshare presentation.
I would also like to separately book my own reservation, for an extra night in NYC, at the same hotel. Also with the exact same room type (King Bed). (Booking through Hilton myself is cheaper than the "discounted deal" the rep had when adding an additional night not covered by the timeshare presentation promotion.)
Thus, I have two nights through HGV, and a third night through Hilton directly.
Doing some research, HGV and Hilton are two separate companies. So I'm not sure if merging my two reservations could be done.
Does anyone have any experience with having Hilton combining the two reservations into one? Could this be done?
EDIT 1: I called the Hilton hotel directly. I provided the confirmation number an HGV rep provided to me over the phone. However, the hotel could not find my reservation. So I do not seem to have any means to provide a confirmation/reservation number for the hotel to look up. I'm not sure how to move forward but to hope for the best during check-in...
