I'm staying at CKS soon and would like to purchase the membership. On the website, for most of the hotels, there doesn't seem to be an option to purchase membership. So, I have to purchase membership to one of the hotels that have the option (such as Conrad Bangkok)? It doesn't seem either membership through Hilton Osaka or Hilton Tokyo can be purchased?
It seems that membership can only be purchased through 15 hotels right now, 8 in Malaysia, 6 in Thailand, and 1 in the Philippines.
