On the 'Where to' page, under "Special Rates", one of the options is: Senior Discount.

Bonvoy is pretty clear about that discount: age 62 and over.
IHG Rewards says: 62 or a member of an organisation like AARP (50+)
Hyatt is even offering up to 50% off at select properties for ages 62 and up.
Some other chains are 55+ or 60+ or 62+.

What is the Senior Discount age for Hilton? Many webites say it is 60, which could be based on an old program, retired in 2008. Others say it is 65. I can't find it on Hilton's own website. Should I just try and find out? In the past I liberally used the rate at IHG but I don't want to mess my Hilton status.
