Universal queues with an ECV

[ChrissyWissy]

Hi All, we are going to both Disney & Universal in October. Not done Universal in a long time so was swatting up on their website. My husband uses a mobility scooter all the time, as can only do a few steps with walking sticks (awaiting hip replacement surgery). On Universals website it states:
With the exception of the Hogwarts™ Express, none of the ride vehicles or attraction queues at Universal Orlando will accommodate ECVs. At those rides which can accommodate standard wheelchairs, Guests may transfer from their ECV into a standard wheelchair that is provided at each location. If you cannot transfer to a standard wheelchair, please see an Attractions Attendant. My question is what can the Attractions Assistant actually do, as my husband wont be able to use a wheelchair as they would be way too low. We will have express passes if that helps. Thanks
