it may cost you around $120-$150HK dollars, it depends on what time are you going to travel, night departure is more expensive than daytime. Me, I got my ticket for $120 from a filipino agent who'm I met inside the free shuttle service going to city of dreams...there are lot of filipinos there who are selling tickets they'll be the one to approach you, but be careful make sure that you get the ticket first before you pay...I took the cotai jet going to HK and it's just 1 hour drive.
