I have MS and sometimes have difficulty with my left leg going numb, feeling like it is burning, or just having the feeling of dead weight. When this happens, I usually use a cane for extra support. We are planning on going to Disney World (husband and I) the last of May and first of June for 7 days. Should I rely on my cane just in case my left leg acts up or should I rent an ECV to get around the parks? From what I have already read, it is better to rent an ECV than rely on the parks having one available for use. Any suggestions would be greatly appreciated!
