I just called a regular Hilton hotel reservation line to speak about an upcoming reservation. When I was done the call he said I have the opportunity to get transferred to the Hilton Grand Vacation team for great discounts. Also, even if i don't want the deal I get 500 points just for listening.
I'm cant vouch for it for being legit but I went for it and the vacation she offered me was pretty good deal. I still didnt receive the confirmation email but she gave me a confirmation number.
If this is real, it is a great deal.
Whilst on the phone, if you are somewhat hesitant about the price she will throw in a $200 hilton gift card , so remember that before confirming
