I was a Diamond for 5 years back in late 90's and just came back in last two years. Tremendously disappointed. No upgrades. Complimentary water and snacks. Yay.
I am at their property in the Outer Banks and called down for a late check-out. "I can do 12pm for you." Normal check-out is 11am. When I told him I was Diamond, the response was that I can do 1pm but will have to check with a manager for anything later. Wow. Thanks, Hilton.
