Hilton HHonors - Hiltons in Southeast US recos?

My wife and I (no kids) are looking for an upscale Hilton somewhere in Florida or in the southeast US with the following attributes:

-new and modern facilities
-nice beach
-impeccable service
-chance for a decent room upgrade if Diamond and using points

Other Hiltons I've stayed at that have the 'upscale-ness' I'm looking for are HHV, Amsterdam Hilton, Hilton San Francisco. Any recomendations would be appreciated.

friendly bump.

I love the powder beaches and warm water at the SanDestin resort. Don't know if it would quite pass your 'upscale-ness' test though. Nice golf, tennis and restaurant/cigar bar onsite. I used the spa in the hotel last year and enjoyed it. I like the shopping, both boutique and outlet. Big convention hotel for Alabama associations because there are very few hotels this nice with these amenities and large convention space south of the state, so rates tend to be high and rooms are all basically the same. We were put on the top floor (16) of the old bldg as diamonds, we wanted the old bldg because the rooms are large and have built-in bunks our kids like. Don't know how old the original part of the hotel is, but I went there w/my parents every summer back in the 80's.
