Your staff at carnival terminal F was exceptional. My name is Frances Hudson. My own scooter wasn't charged and I thought I had left my charger home. Your staff and an older porter pushed it out of passenger traffic. I rented one of yours. On several occasions the scooter just took off and wouldn't stop even when I released the controller. In fact it collided with objects and passengers. This was not operator error as I've been using mobility scooters for years now and this is the first time I've experienced anything like this. Fortunately no one was injured and were all kind about it. Please check this scooter out before someone is injured. Let me say again how pleasant and helpful your staff was at terminal F and D. They were a life/cruise saver for me
