Here now. Initial conclusion: very good, just like the pre-covid Sakura Club experience that I remember, although it's missing some aspects. Staff are just as fantastic as before.

Missing elements: Japanese whiskeys, bathroom amenities have switched from Shanghai Tang to Byredo and the shampoo/conditioner/body wash are no longer individual but accessed through dispensers, lunch still not served in Sakura (but between breakfast/dinner at Sakura and the $25/adult up to $50/room food credit that can be redeemed at Estuary I don't miss lunch service at all)

Good: food is still at a very high level with added choices through the chef's hot station, breakfast is excellent (better than eating at Blue Willow downstairs)
