Celebrity Wheel Chair Service on embarkment and disembarkment days in Sydney?

[caseum]

Dear fellow cruisers,

 

Has anyone used the wheel chair service on the embarkment and disembarkment days with Celebrity cruises in Sydney?

 

Embarkment

• If arrive by taxi or car service, how close can the car get to the entrance of the Oversea Passenger Terminal? 
• Are there ample of seatings for passengers waiting for embarkment? 
• Is there any free wifi within the terminal?

 

Disembarkment

• I heard that for self-walk off, people start to line up early like 645a.  I wonder for people that need a wheel chair for disembarkment and have an early flight, would they be provided the wheel chair service as early or even earlier than 645a?  Or they would have to wait until after the self-walk off crowd dissipated before they will be wheeled off the ship?
• For the people who had self-walk off the ship, how was the walk (flat surface? downslope ramp?) and how long was the walk to the taxi rank?

 

Feel free to add additional information that is not in my questions.

 

Thank you!
