I just spent two nights here last weekend as a diamond.

I booked the standard room and 24hrs before stay, it was upgraded to Hilton King Executive (mostly just a higher floor room with access to the Executive Club) via the Hilton app.

I initially walked up to the lobby check-in, but was ushered up to the club lounge on 11th floor for a check in, and had a concierge accompany me the whole way.

I was slightly early (~1 pm??) for check in, so my pre-assigned room was not ready. I was asked if I would be willing to take another room that was ready, and I just took it (it was 10th floor vs the 11th floor room that was pre-assigned).

As a diamond, I was offered either full breakfast at the restaurant, or breakfast at the lounge. The breakfast at the lounge was ok, but I highly recommend the buffet breakfast at the restaurant.

The Executive Lounge was nice - offers breakfast (6.30 - 10.30/11), tea (3.00 - 5.00) and happy hour (5.00 - 7.30).

The room is large ~500 sq ft, and very nice. I'd probably put it at the level of a Conrad or Waldorf Astoria, more so than a Hilton. Service was impeccable. They also have a pool with lovely cabanas.

Overall, I had a lovely stay.
