I pay more attention on bath amenity always. And Aesop is my preferred one.

Park Hyatt Busan: Stayed there last Dec. and found Le Labo Bergamote 22 series (50ml) only. Larger size can be found in Diplomate Suite and Presidertial Suite.

DIAMOND members will receive a set of Chidoriya as welcome bath amenity. In RIRAKU Spa, you can buy a larger one. I love it very much.

Hyatt Regency Naha, Okinawa: As it will open in this July, I found ACCA KAPPA used in all rooms and suites, from its official website.

Moreover, Aesop can not be found in three Hyatt properties of HK. HR Sha Tin and HR Tsim Sha Tsui offer portico|SPA series.
