My flight landed at terminal 1, Hong Kong airport. After immigration etc (took 10 minutes for me) turn right to the end of the hall, then turn left, follow the crowd, take the elevator down to level 3, now you are at the bus terminal. Turn right and you will see a sign B4. If you are not sure about the way, just ask some officials, I had no problem to get adequate answers about the way.
Have a 10 HKD bill with you for the B4 bus ticket, no exchange. After 15 minutes you are at the Hong Kong port, then immigration out of Hong Kong (took 3 minutes for me). Then you buy bus ticket to Macau, HKD 65, or 33 if you are 65+. They dont accept VISA card so bring cash, they will give you change if you have larger bills. Bus to Macau over the bridge took 45 minutes.
After Macau immigration (took 10 minutes for me), you go straight out to the bus terminal. I arrived after 7.30pm, so no free shuttle to the outer ferry terminal. But no problems. I did bord bus 102x, ticket price 6 HKD or MOP. I had a 5 hkd and a 2 hkd coin, paid with them, no exchange is given. This bus will stop outside Wynn casino, close to Starworld and close to many hotels in the central of Macau. You will not miss it, the speaker in the bus will tell you when the bus approach Wynn. I walked then to Holiday Inn Express, took 7 minutes.
So instead for paying ridic money for going direct from Hong Kong airport to Macau over the bridge, just pay about HKD 80 , 3 buses, and you are there. I also doubt it is faster. I saw many travellers with big bags, so not a problem.
