After a lot of research on Macau saunas, I found a Chinese website which talked about the newly opened Majesty Spa at the Harbourview Hotel in Fisherman's Wharf. The Google Map location of the hotel is accurate. The sauna is super new, so all the facilities are nice and sparkly. Its also big, with 3 floors and a lounge that seats 50+. Smoking is allowed but I didn't see any smokers. I went to visit on a weekday at noon, which was a mistake. There was only 1 girl available, and 2 others came within 30 minutes, but I wanted a bigger selection. Around 1:30 a foot massage auntie showed up, which I also declined. But then some young Viets came by to offer shoulder and thigh massages, so I took them up on their offer. During the massage, they tried to upsell me on the private room for 3888 MOP (500 USD)!
Let's talk pricing. I attached a menu picture which lists prices by race on the left side. The first price is the entry fee, which is comped if you choose a WG. The second price is a veggie massage. On the right side is the list of public lounge services, like the arm and thigh massage pics I posted. It's strange to me an arm massage costs nearly as much as a HJ tease (thigh massage, but actually 70% HJ with no release).
But the weirdest part is that the most expensive things are "mixed massages" (massage plus HJ) as seen on a separate Chinese menu which I will try to attach in a reply. True, these massages are from 2 or more beautiful women at once, but still, nearly $1000 USD for a rub and tug???
So back to my experience: after the "thigh massage" I was ready to

so I called for a lineup with whoever was there (3 pm). This time it was 6 more girls, mostly Viet. None were great, so I ended up choosing a Chinese for 2888 MOP. She asked if I wanted a theme room, but my Chinese wasn't good enough to understand which themes were available, so we just went to a standard room. One side had a walk-in shower room with tub and table shower, but we just took normal showers. Close-up, I could see she was older than I thought, maybe mid-30's. But her body, attitude, and service were all great, with a catbath on back and front, lots of deep rimming, and a long BBBJ with 69. CFS was unremarkable, just going through a few positions.
I got another shoulder massage, ate a lot of free food, and went to the hot sauna a few times. I stayed at the spa until the next wave of WG's at 6pm. At this point there was still only 1 other guy in the huge lounge. The lineup was 10 girls, 3 very plain ones from Vietnam, and the rest were in the 7 to 9 range, but costing more than 3000 MOP.
In conclusion, I might come back at some nighttime, and bring a friend to chat with. At these prices, you're paying for selection, which is not there earlier in the day.
