I haven't talked to anyone with disabilities or seen anything written yet about accessibility. I have seen some videos, but they were pretty dark showing the boarding area, so it's hard to say how it will be.
We won't be to WDW until October, so won't have first hand until then.
There are some things I know:
- the LINE is wheelchair accessible
- the original Maelstrom boats were re-used
- none of the Maelstrom boats were accessible or transfer assist boats
- getting into the Maelstrom boats required a high step/lift over the side to the seat and then another step to the bottom of the boat
- the Maelstrom boats were similar to the Pirates boats, but with a higher side
- the Disney website and app list it as 'must transfer'
What I don't know:
- whether or not there is or will be a transfer assist boat with a opening side or anything to make transfers easier
- this was a 'cosmetic renovation' and the ride path was left as is for the most part, so I am not sure if a requirement for making an accessible boat (like there would be for an entirely new attraction)
What I can't confirm, but am still sure of:
- there will not be a wheelchair accessible boat because there is a steep climb and a drop during the attraction (that has not changed from Maelstrom)
This is the old Maelstrom boat, which is being reused for Frozen Ever After. You can see that the sides are higher than Pirates.
This is the Splash Mountain boat.
We felt the Maelstrom boat was a similar height (or a bit higher) lift over the side.
Before Maelstrom closed, we had gotten to the point where we felt it was too difficult to lift our daughter into the boat - mostly because the lift is high. She is not big; she's only 5 feet tall and about 81 pounds.
We actually had plenty of space when we did ride Maelstrom. We loaded in a clear area just before the regular load area.
