I kept the idea to myself during our stay to avoid dampening my companion's enjoyment. But she said it anyway over lunch: "This is not like a Grand Hyatt!"
Before the hotel visit, we were wondering whether to book for a two-night stay to make it a more restful one. We were glad we stayed for one night only.
The room (a suite) was exceedingly spacious, especially for a brief stay.
In order to sleep more properly, we had to put some extra effort into getting used to the loud-noise air-conditioning: constant fan / air-movement noise, regular cranking sounds of the air-conditioners turning on and off.
In order to have coffee, we had to wash the handle-less tea cups (only two tea-cups provided) for Chinese tea.
Grand Hyatt Macau put a lot of effort to down-manage my expectations. One day before the scheduled Monday check-in, they had a Reservations Guest Service Officer e-mailing me saying the non-smoking room we booked would be "subject to ... availability".
Two hours later, a Reservations Team Leader e-mailed to say: "The dates of your forthcoming reservation fall over a particular busy period for the hotel, hence we regret to inform you that we are unable to confirm your requests on this occasion. As you are our Gold Passport member, we will place you on priority should there be availability."
During our stay there, we had the impression that the hotel did not have many guests, judging by the traffic in the lobby, the number of check-in / check-out counters opened, and the less-than-half-full restaurants / lobby lounge.
At check-in, the counter staff member gave me a nicely printed letter showing the service hours of the Grand Club Lounge (part of our original Club Room booking for a small extra fee of US$30 approx):
=> All-day light refreshments: 11am - 10pm
=> (breakfast: 6:30pm - 11am)
=> (evening cocktails: 5pm - 7:30pm)
I said the only times we were available to make use of the Club Lounge was after it had closed at 10pm or after we had checked out according to the hotel policy of check-out time at 11am. And I asked for the Club access as well as the small extra fee of US$30 approx to be cancelled. She said we could go to the Club Lounge for breakfast, and then without saying a word, proceeded to check us in and handed us the key cards, as if I never made any request for a change.
I had to raise my voice and tell her to get the Assistant Manager right away. This she was able to do very promptly, without making a sound. The rest was acceptably sorted out by Florence, a senior and obviously much more competent staff member.
So we managed to change from the originally booked Club Deluxe room (in the Grand Club Tower at one end of the hotel) to a Grand Suite (in the Grand Tower at the other end of the hotel), which was practically right on top of the The House of Dancing Water theatre (my sole reason for choosing Grand Hyatt Macau).
We were also able to make up for the time lost at the check-in counter by taking a short cut through the hotel's Beijing Kitchen restaurant to get to the theatre for the 5pm show.
