Hilton HHonors - On property benefits when booking via 3rd party?

I am thinking about booking an expedia "vacation package," and the Las Vegas Hilton is the hotel that keeps coming up. Just wondering if Gold benefits are extended (exec floor, etc) when one books this way - regardless of HH points earning. Thanks.

There is no executive floor benefit at the Las Vegas Hilton even for a Platinum who books on Hilton.com. The only benefit could be the breakfast buffet and I did get it a few times at some Hiltons on Priceline. I do not know if it is easier to get with Expedia.
