Hi, I have not been to AKL since Kidani opened so I can not help you with a room location. But I am sure there will be others on shortly to help shortly.
You did mention that you were exhausted by the end of your trip from pushing your mom in her wheelchair. I don't know if this would be something that would work for you and your family, but you may want to look into renting a
ECV from a private company for your stay. My DH has a disablity the makes it difficult to walk long distances. He is fine at home and in our normal daily life, no problem.
However, when it comes to theme parks or zoo's and walking for miles a day, standing and waiting for long periods we just rent from a outside company. They deliver the ECV directly to your hotel, it will be waiting for your mom at the front desk or bell services. The daily cost is less then renting from Disney and the units are much better quality and easier to use. In addition you have use of the ECV for your entire trip, at the resort, DTD, parks, shopping everything. They break down/reassemble quite easy into about 3-4 pieces and fit in most trunks. They are not difficult to put in the bus lifts and the drivers have always been very helpful and considerate. It is so much nicer then pushing him around and he is much happier because he is not dependent on me. We both have more energy and enjoy our trip much more. As I said before, this may not work for you and your mom, just a suggestion that has worked for us. Hope you have a wonderful trip.
