Do not mind dealing with the HG agents. Standard procedure, and you will never see them. They just take care of the times and tell you when to come and to which hotel. At the hotel you'll call the agent again, and he tells you to which room number you should go to.
No massage from HGs though. At some point you'll want to take the one hour ferry over to
Macau and visit one of the saunas. You'll get one hour with a very hot girl you can select from a line up, and in the room will get a soaped up body massage, and more attention to your lil bro.
