So I'm seriously considering using an EVC for the first time on my next visit, my feet and knees especially with my arthritis would probably really hinder my getting around and I don't think I could stand for more than 20 minutes and we only have 1 day to do both parks. My question is for those of you who have rented one at the parks is it a hassle to rent and get around, depending on the crowds I'm wondering if it would be harder to navigate. We are going on our next trip the first week in December, I have never been this time of year. Thanks
