Thanks she can sit on her own and has good trunk control. I think she will do well on splash she has been on the safaris ride several times before.
for the peter pan ride in MK do they stop that ride at all to allow riders who transfer to get on or off.
These attractions have moving walkways which can't be stopped:
Peter Pan
Tomorrowland Transit Authority (also called People mover). This has a steep moving ramp to get to the 2nd floor station/boarding area. It also has a moving walkway to board and exit and another steep moving ramp to get back down from the station to ground level.
Cheshire Figment checked on Peter Pan for us a few months ago; according to an attraction area supervisor, Peter Pan can't be stopped or slowed during the day.
Sometimes for the first ride of the day or the very last ride of the day, they will do a special run for guests who could not board with the walkway moving. They have the attraction empty of guests, with the moving walkway stopped. Then they load a group of guests onto the ride's Pirate Ships until all the ships waiting on the loading area are filled. They run a cycle of the ride with just these passengers and when all those pirate ships have returned to the exit point, they stop the ride so all the guests can get off.
Thanks she loves that ride and has since she was a baby. She is 7 now and just between 42 and 44 inches and weighs between 45 and 50 pounds most of which is dead weight so I am pretty sure I will not be able to jump on or off of that ride w/ her w/out hurting one of us. Is there a list of rides like peter that are not easy to transfer onto.
If you follow the link in my signature to the disABILITIES FAQs thread, one of the posts on the first page of that thread has the list of attractions with warnings. As was already posted, WDW lists the attractions with warnings, but it is up to the guest to decide whether the warning applies the them.
On page 2 of the disABILITIES FAQs thread, there is a list of attractions for each park which indicates whether it is accessible or not and information about which are difficult transfers.
For Splash Mountain, part of the regular and Fastpass line is accessible up to the point where the line reaches a set of stairs. At that point, there is an alternate path marked with a wheelchair symbol for guests who can't use the stairs.
You do NOT need to have a GAC to use that area of the path if you have a visible need - such as a wheelchair, walker, ECV. You DO need a GAC or sticker to use a stroller as a wheelchair in line. That path directs you to a waiting area at the exit side of the attraction. From there, you can bring the wheelchair or ECV as close as you need to the ride car.
Again, you do NOT need a GAC to bring the wheelchair or ECV into the accessible boarding area.
My DD can't stand and the problem we have had with Splash Mountain is that the side of the ride log is very high and the space inside the ride log is very tight. When she was smaller, she rode many times, but has not ridden in several years.
She was larger than your DD the last time we rode with her; we found the challenge of lifting 70+ pounds of dead weight high enough to clear the side of the car was very challenging. Especially, given the small amount of space inside the log. Here is a picture that will help explain.
