Having just completed chemotherapy and radiation, my strength is not totally back which limits my ability to stand in lines and do extensive walking. When walking, I can pace myself and take breaks before I wear out. It's the standing in lines that will wear me out however. Does anyone know if there is a way to avoid the standing in lines without having to get the wheelchair? Also, if I start to wear out half way thru the park, do we have to go back to the entry to get a wheelchair or are there other places to obtain a chair inside the park? Thanks for your answers!
