call their 1888 ICHOTELS and they will verify that there are indeed 2 HK locations, sorry you cant find the 2nd one on google.

But the people on that 800 number support team have access to all the same information that the front desk/event staff has at the actual hotel. I worked for OMNI hotels for 4 years. If its on the server for any branch, the support team is able to view the information

I cant make that international call right now, the number provided gave me some reply about invalid country code or something
