Our experience at Na’vi River ride was definitely mixed. From the boarding area, you can also see the unload area. Each area holds 2 boats at a time, which come to a complete stop for loading and unloading. The photo shows the unload area. The loading area is to the left of the photo. As we were waiting, we saw one group park a wheelchair, the person walked to the boarding area and got on there while the CM took the wheelchair thru a gate into the unload area. A little about my DD - she is about 5 feet tall and weighs about 80 pounds. She has cerebral palsy, which is a movement disorder. She has mixed type, which means she has elements of different types of CP. Her predominant is spastic quad, which means she has very tight and stiff muscles. But, she can switch quickly from being as stiff as a Barbie doll to as loose as a rag doll. When she get excited, everything straightens (goes into extension) . This makes sitting unsupported difficult because she is straighter at the hips than she should be. We told the CM who was sending people to boarding that we did not know if we would be able to get our daughter into the boat. The CM asked if she could walk a few steps. We said no and she asked if it would help us to be able to park her wheelchair closer to the boat. We said that should be helpful and she directed us through the gate to the unload area. We had a party of 5 and were told that our entire party would fit in this boat. It looks small, but actually would have been comfortable for 4 seated in the back. We were told to take our time and load DD in either row - whatever worked best for us. We chose the back row and loading was actually not that difficult. We parked her wheelchair close to the boat and had one person inside the boat standing on the boat floor to ‘receive’ her. My DH was outside and lifted her in a seated position to the ‘receiver’, who set her on the seat. The ride itself was good, until it wasn’t. About halfway through the ride, she got excited and went into extension. The ride seat is not very deep, so when she went into extension, her bottom was partly off the edge of the seat. She tried to push herself back on and we tried to pull her back, but the seat has a rough, non slip texture - kind of like sand was put into the paint. I don’t know if the rough texture hurt her back and bottom where she was pressing against it or not, but she was definitely afraid of her bottom slipping off (she told me later). Getting off was not bad. I stood on the floor of the boat and stood her up. My DH ‘received’ her and put her in her wheelchair, which was parked a few feet away. So, our experience on Na’vi River ride was definitely mixed. Getting on and off was not as difficult as we thought it would be and she said afterward that she liked the ride. She does not want to go on again though because of the ‘sitting’ issue.
