scooters on boats?

Can my elderly parents bring their electric 4 wheel scooters on the boat to DHS? Thanks

I took my ECV on the boat from EPCOT to Beach Club with no problems. They will put a ramp down at the back of the boat for boarding.

i can't think of one place i wanted to go to that i couldn't on my EVC.

The only boats that might pose a problem are the smaller boats that run in the seven seas lagoon to GF, WL, and Ft. Wilderness. They have accessible boats, but they also run smaller ones. I think on maybe 3 occasions during our last visit we had to wait for a second boat (we were staying at the fort and my brother was using an ECV) The ship captains were always nice and radio'ed for the larger boat for us.

We only had problems using the smaller boats on the 7 Seas Lagoon and here we only tried it to get from Ft. Wilderness to MK. With the others we just used the monorail. The drivers were great to work with us, though. It was after seeing the Hoop-de-doo and was getting fairly late. We were actually trying to get to the Contemporary and had to wait about half an hour for a larger boat. It was chilly so they made a special stop for us at the CR instead of making us transfer at the MK to a monorail since we were the only ones on the boat. I didn't expect it and wouldn't expect it in the future but it was very nice (Mom's RA was not responding well to the cold).
