I am planning a last minute trip with my dd son. I think I'm going to need to use an ECV this time -- walking has gotten very difficult. What arrangements will the airlines make for you to btring your own? Is it better to rent for the week ( we'll be there 6 days) or rent at the parks?II'll be renting a car and do have a handicapped tag for parking. Will I need to get a certain size car to accomodate?. My 20 yo dtr has always gone with us and when I can't walk she's pushed me in a wheelchair --- she's not going to be able to make this trip so I'm on my own. My son overloads easily so we may be in and out of the parks several times during the day. This board has been terrific for info --- thanks in advance for helping with this.
