Hello all! We have a trip to WDW coming up in a month, and I wanted to get some feedback on renting an ECV scooter, if it would be possible with someone who has wrist/hand issues. My husband will need a ECV scooter, as he had foot/ankle surgery and just starting to bear weight on his foot. The other issue is that he has nerve damage to his right hand/wrist and has a poor grip. Would this be an issue, as I noticed in the photos you have to grip a lever in order to make the scooter accelerate?
