Are you counting Hilton spent or using the Hilton AMEX to qualify???

You must be a big spender to rack up 95000 base points and not have had either 60 nights or 28 stays in the last year. You might check to see if you had either 60 nights or 28 stays. If so, you didn't lose diamond.

If you really didn't requalify, you could always ask nicely. But that probably won't work. I stay 2 nights a week and so I tend to break them up and stay at two different hotels. That didn't benefit me this quarter but I'm well over halfway to diamond requal. That may be your fastest option.

But, really, other than some extra bonus points there aren't any huge everyday differences between gold and diamond. Some will argue about the Diamond "force" but most of us won't use it every week.
