I understand people bring electric wheelchairs and ECVs from outside vendors that can be taken between and outside the parks. I just don't understand why they occupy multiple (4-5) seats for their vehicle and THEN an additional seat(s) to sit in. I inquired with the bus operator who said it is safe for them to sit on their vehicle when it is secured and tied down, it just seems inconsiderate to occupy so many seats particularly after occupying a solid 10 minutes of everyone's time to get their vehicle onboard and properly secured.
