I'm not sure what Disney does, but each time I have rented from Walker thay have included a a small plastic bag which hangs from the lever that controls the tiller angle. In this bag is a small, clear plastic cover with an elastic band around the rim to go over the control box. With that on you can still work the controls and see the power meter. That is all that is needed. The batteries and everything else are OK. You might wasnt to use a ponco to help keep yourself dry, and also carry a towel to dry off the seat if necessary.
