Hi Sally! i got a response from disney concerning the aquaduck and handicap accessibility. Here it is:
7/5/11
Dear Lisa,
Thank you for your interest in a
Disney Cruise Line vacation!
I would be happy to assist you.
The entrance to AquaDuck is only accessible by stairway and is not
wheelchair accessible. However, if you are able to assist the Guest, up
the stairs, she will be able to ride the AquaDuck. Please keep in mind
the entrance of the AquaDuck is on Deck 12 but the ride launch area is
on Deck 16. Therefore, there are 4 decks of stairs to climb. For more
information, you can speak with a Crew Member at the AquaDuck's
entrance.
In addition, the minimum height requirement to ride AquaDuck is 42. If
you want to ride the AquaDuck as a single Guest in the raft, the minimum
height requirement is 54. Guests who are under the age of 7 must be
accompanied by a Guest 14 years of age or older. However, both must meet
the minimum height requirement. At this time there is no weight
restriction to ride AquaDuck.
Due to safety concerns, Guests who do not meet the minimum height
requirements are unable to ride AquaDuck.
I hope this information has been helpful. If you require further
assistance in planning your visit, please feel free to contact us.
We look forward to sailing with you!
Have a Magical Day!
