A few data points, observations, and nit-picks after staying here for a single Saturday night on a cert as a Glob in Aug 2021. The short version is: Everything already mentioned in the thread is pretty spot on. The hard product is generally to Park Hyatt expectations, service is good (not great)...but operationally there's a lot of inconsistency. Overall in my opinion definitely missing a few things to truly be considered a "flagship" caliber property for Hyatt

• In app, offered upgrade to an ADA Park Suite with immediate availability at 1:30pm. I still checked-in at the front desk around 4pm as I needed a tub for my infant - got the Park King that was booked. No mention of an upgrade availability, but also had to wait 45 mins for the standard king room to be cleaned.
• Valet parking was available, but s-l-o-w. Doorman who took the keys said either call down ahead 30-45 mins to get your car OR for 5 minute service just walk to the garage entrance on 58th behind the hotel, and the parking company (ICON) can deliver the vehicle much faster. I'm sure some of the slowness is due to staffing...but an observation from my dashcam, The slowness is just due to an inefficient operation. When dropping off in front of the hotel, to get to the parking garage the valets have to drive a half-mile loop down 57th, right on 8th ave, another right on 58th with 6 traffic lights. Then the garage elevator is a 45-60 second ride into a very tight garage. In short, there's no "fast” valet parking
• I’m not sure if the room was turned too quickly or the property is tightening up on amenities but there were a lot of missing courtesy items in the room that I expected to see - half the mini-bar was empty, the laundry & shoe bags weren’t there, there were two robes but only one pair of slippers, and perhaps its just covid but there was no stationary/pens. No welcome amenity, not even fruit.
• The rooms are definitely showing some wear and tear. More than a dozen of the tiles in the bath had cracks throughout (to the designer's credit they blend it well with the stone material), the swing-down reading lights in the headboard are loose (as in if you don’t pull gently they will come “out” of the headboard), and even the roll-in crib was chipped and missing paint.
• The tech in the room is also aging - the on-screen guide on the TV never loaded the program listings the grid guide just shows “coming soon", the bedside analog clock needed a new battery, and the rubber on the iPad case was reverting making it sticky.
• I was surprised to see two attendants/lifeguards working both times we used the pool - but with the relative crowd the pool area drew it made sense considering that early ever chair was being used. It was primarily families, and I felt pity for the one gentleman who was trying to get some laps in. But even with two attendants working the pool experience was disapointing, the underwater speakers weren’t working, there were piles of calcium flakes accumulating in the corners, but most disapointing of all, they ran out of towels during both pool sessions. No towels available in the locker rooms or on the pool deck - and the attendant said they would not be available until the next day. So we saw more than one famly trek to the elevator dripping wet…
• Granted it was a hot weekend, but it seems the default service recovery is to offer up a bottle of water. It was almost comical how each time a staff member apologized for something they offered a bottle of water - from the wait to the room, the wait for the valet to write up the parking ticket, needing to wait for a bellman, a delay with the concierge, I was always offered a few bottles of water. Everone was extremely friendly and for the most part geniuine but is bottled water really the right guest recover tool?
• A few items on the room service breakfast menu have seem price increases (Steak & Eggs and the NY Breakfast are now $56 (up from $45), and smoked salmon side is $21 (up from $14). - they did bill us for everything over $135 ($45 x 3)
• They’re promoting two additional “amenities” with some retail partners - we didn’t shop this trip so we didn’t take advantage, but the hotel conceirge is supposed to have Nordstrom “gift cards” good for free coffee at the Nordstrom Coffee Bar, and showing your Park Hyatt NY room key at the La Labo store on 65th is supposed to net a “5-piece discovery” set
