I will be alone with my 5 year old granddaughter. If she gets too tired to walk or if we are in a crowded area where we might get separated. Is it ok for her to sit in my lap? I don't want to lose her ****Was just asking a question since I know she will be fine most of the time but if she falls asleep or walks too slow people will run over her. She is too heavy for an umbrella stroller. My son will be with us some of the time. I have my own ECV at home and am very apt at driving it even with a child. I have seen some horror drivers at Disney and understand your concerns. I'm more concerned about her being run over. AS an experienced ECV driver I can tell you that the problem you have there is that so many people are using them for the first time. Many times I myself or my son have had to drive someone else's scooter onto a bus to save them from themselves. I have 12 years experience and have often been told by bus drivers how excellent I handle the scooter. Again the problems of some ruin things for others.
