Hotel: Ritz-Carlton Millenia, Singapore - April 2023 (1 night stay)
Room: 1 King Marina Bay View
Rate: USD 511 before taxes
Check-in time: Not used, arrived around 9 pm
Guaranteed 4 pm late check-out: Confirmed at check-in and used for 4 pm
Upgrade: Not offered, and didn't bother asking because it was just 1 night, and we were tired from a long (and delayed) flight from the US
Breakfast: Buffet at Colony; I think also available from room service but we ate at Colony
Complimentary Wi-Fi: Yes
Unique Property Amenity: USD 100 F&B credit, which they converted to S$120. Not a great exchange rate but could have been worse. Used on room service and [accidentally] at the Colony Bakery (see comments).
Comments: The property does not participate in Marriott Bonvoy, and they repeat it constantly (in messages, emails, welcome letter, in person), just in case. I assumed the F&B credit could be also be used at the Colony Bakery, but turns out that wasn't the case. However, I mistakenly ended up doing check out at the Japanese concierge desk (reception was well hidden), and they were nice enough to offset my Colony bakery purchases with F&B credit. Ended up with a 50 cent balance after applying the credits, and true to FHR rules, I had to pay that with my Amex.
