We are going to the Poly next month and this will be the first time that my mom will be using an ECV. I want to put in my building request but wonder if it is suitable. Are all the rooms at the Poly large enough to park an ECV in? Can you take them on the elevators at the Poly or do I have to stay on the first floor. We do not want a handicap room though as my mom will only need to use the ECV in the parks and not in the rooms. Is using an ECV putting an end to my dream of Samoa third floor like we had on our last trip?
