I stayed here November 14-18. Some highlights:
- Did NOT get a suite upgrade as a Diamond member. Perhaps this has to do with the length of my stay and right in the work week rather than a shorter weekend stay. Did get a room with a pretty good Manhattan skyline view.
- Was treated like a VIP, despite not getting the suite upgrade. I was mildly surprised by that -- I figured this hotel's location would mean its guests would have a higher percentage of Diamonds than your average Hyatt, so I'd be just another guest. But I was contacted by email by a concierge from her personal Hyatt email account (not just the automated email system), she offered to help me in any way she can, and even came out from the back to meet me at the check-in desk, telling me to definitely choose the Diamond 1W points bonus but she'd arrange for the food & beverage amenity to be sent. She continued to touch base with me by email during my stay. Later on my first day, I walked into the restaurant in the mid-afternoon when they were not serving to check out the great view, and a manager with whom I made small talk made a nice generous offer in regards to dinner, as a welcome gesture to a Diamond member.
- Loved the hotel's proximity to the Exchange Place PATH station. The station isn't technically attached to the Hyatt, but even if it was raining cats and dogs, you could walk out of the hotel's doors, keep walking under the building overhang, and make a dash of about 20 yards to enter the station. As noted upthread, it's possible to take inexpensive public transportation (#62 bus [or AirTrain and then the more expensive 1-stop Amtrak ride] to Newark Penn Station and then PATH) from the Newark Airport to the Hyatt pretty reasonably. Several nights, I popped into Manhattan just to grab takeout for dinner or to meet a friend for dinner, and it was very easy. The shopping mall that's a 20 minute walk north is just 1 stop on PATH, and given frequencies of PATH during most of the week, slightly faster on PATH than walking.
