Ok. I’m going to say it. If waiting an addtl 5-8 mins and possibly having to stand on a bus is going to be an issue, then perhaps this type Transportation isn’t for you. You could rent a car, use Uber.
Disney is expected to provide ‘equal’ treatment to all its guests. This means that a family with someone using a
scooter gets to board the bus together. There is signage at each bus stop suggesting that parties if more than 6 split up.
As I have said, repeatedly, I’m at WDW a lot. Probably spend at least 40-60 days a year there. The times I’ve seen two scooters on one are very limited. The number of times I’ve seen more than 5 or 6 family members boarding with an ECV are also limited.
I’m sorry you’ve had this experience. But there is no way Disney is going to limit the number of people boarding with that ecv guest to one. Just isn’t going to happen.
