We recently completed our 8-night stay. First 7 nights booked cash + SUA into a grand suite. 8th night was on a FNC (Yes, I took the chance considering many past reports of an SUA stay automatically combining into extra nights on certs having issues with SUAs getting removed. We experienced no problems, and in fact, seemingly the hotel never combined our stay at all.)

Some quick notes:

Check in was with a newbie so he didn't really go above and beyond and also wasn't knowledgeable on the benefits. Had to pull in another colleague to get some answers to a few of our questions. As mentioned in recent posts, there is no longer a happy hour benefit for globs in the restaurant. There is no breakfast option in the restaurant. Everything is lounge only. The destination fee does offer $10 daily F&B credit, which I was told is just automatically removed from the hotel bill. In the end, never used it even once so unable to confirm.

We received the Grand Suite on floor 2 which was a bummer for the kids (they always like high floors) however I don't think this hotel offers much views anyway so it was perfectly fine for us. I think the Grand Suites are all on the opposite end from the elevators so you'll have to do a lot of walking. We were able to check into ours at 1:45p so that was great that it was ready for us. However there was no rollaway bed and, oddly, the gigantic living room had not a single trash can. So I texted the front desk while we were off property and they promptly replied that both would be delivered shortly. When we returned to the hotel that night, everything had been placed nicely in the room.

Next day I stopped by the FD to inquire about the metro card (destination fee includes one metro card per reservation) and was very matter of factly informed that if I dont pay the destination fee I don't receive the benefits. Seems I got the strict agent. Oh well, she wasn't mean or anything so I thanked her and left. A few days later I needed to break a larger bill at the FD so I again asked about the metro card, this agent quickly grabbed one for me. So...YMMV

Day before our checkout (for the 7-night portion of the stay) I stopped by the FD and the very kind agent tried really hard to find us an upgrade for night 8. I knew the Grand Suites were not available so we wouldn't be able to stay in our room. So the preference order was to either get into another suite, get onto the club floor, or get a room near our current room for ease of transfer. She really wanted us to get that suite (more than me it seemed) and spent minutes trying. So she put us in a regular room on the club floor and told me to check back in the morning for a suite as availability often changes. I did not check back the following morning.

Lounge is quite good. Imo the most extensive selection of any lounge in the US. Quality is adequate-to-good. The drawbacks in my opinion are very limited seating and pretty minimal change from day-to-day. Breakfast is always the same. Evening service seems to have maybe a three-day rotation but even the rotation is very similar dishes (eg lamb meatballs and beef sliders one day, becomes lamb sliders and beef meatballs another day). We're spoiled having been to so many lounges in Asia, so I do recognize that this is quite nice for the US. And the service in the lounge was always excellent. Shout out to them.

At check in I mentioned that I was going to have a vehicle overnight on one particular night. I asked how much it was and he told me $63/night for valet. Was hoping he might suggest a comped night of parking haha. Actually as I am typing this now I'm realizing maybe I could have pointed out my free night at the end of the stay (not the same night I'd have the vehicle). Oh well, it didn't occur to me at the time. Instead of valet, I used spothero and for $19 I reserved parking for 12 hours very close to the hotel. I had the option to extend for approx $1.50/hour, so seemingly the prorated cost of my original booking. And when I went to park, lo and behold, I was in the Grand Hyatt's parking garage lol. So very convenient.

Happy to answer any questions...
