I try to visit the Waldorf at least once a year. Whilst the rooms are a bit long-in-the-tooth, the recent refurbishment of the Park Ave entrance looks splendid. It has been restored to its original layout and look.
I’ve been a Diamond VIP with HH since 2005, and the on-premises benefits have clearly diminished over the years. I do have a standing arrangement with the Diamond Reception and am always taken care off very well. One recommendation is to book a room on the Concierge level which will give access to the “smallish” Executive Lounge. When I have looked, rooms tend to be about $40-60 more a night.
For me, the location is ideal for NYC visits and as Goldcardsaplenty, I find this to be a lovely break from my usual glass, steel, concrete hotels I use around the world.
