I wanted to mention 2 things regarding
ECVs (also called "scooters" and "electric carts):

The smallest child in the group also got a free ride on papa's lap sometimes, so that was fun for papa and the little one loved it.
If you rent an
ECV from the parks, they do not allow anyone under 18 to operate or ride on the ECV and they also do not allow more than one person on the ECV at the same time.
Many of the off-site companies have the same provision in the rental contract. I know it was a provision on the rental contract when we rented one from Randy's this March said that and people have posted their rental contract for other companies also said the same.
This is a safety provision. A small child could fall off the
scooter while it is going, accidentally grab or hit the controls while it's going and cause the scooter to go out of control or the child could get in the way of the driver. I have seen all these things happen. Someone can choose to do it on a scooter they own, but if renting one, the company that owns it might very well have rules against it.
I recall that he was directed to the handicapped gate/entrance on almost all the attractions, which meant the rest of our group was permitted with him, but we were a small group.
MK and Epcot are older parks and some of the attractions don't have wheelchair accessibility thru the regular "standby" line. If you traveled before 2000, especially to those parks, you would have encountered more handicapped entrances. All the Fastpass lines are wheelchair accessible and many recently renovated rides are accessible.
AK and the Studio were built with Mainstream Lines (which means the standby lines are accessible and wheelchair/ecv users wait in most lines with everyone else). There are some shows that have limited numbers of wheelchair/ECV spaces. For those, they do pull wheelchair/ECV users out so that they can make sure they don't have more ECV/wheelchair users waiting in line for a particular show than they have room for.
I'm mentioning this because some people in the past have posted complaints because they were not brought to the handicapped entrance in all attractions.
