I agree with you. But here is what doesn't make sense to me. Why was HK$ leaving the room just as the gang was getting back from the airport? Didn't he think they were going to return? Did they get back a lot earlier than he thought they would, and took him by surprise?
It would really be helpful to know exactly where KEG was then.
It sounds (to me) like Moe and Taz brought Bridget and KEG back to the hotel with them. I'm curious why HKS chose to meet them all in the lobby and then go with them back to the room where (it appears) he and KEG left from to go to the boat.
