As of today,
the website doesn't have the notice about reservations not being available. Searching, it looks like there's only one day available to book though: December 20th. I guess it's a mistake and it'll get cancelled but I booked anyway. Here's the rooms and prices for anyone interested:
Considering base room it's cheaper than M.O and 4S... But more expensive than the Peninsula and the Rosewood... Wonder if it is the correct price range?
