We will be renting an ECV for my mom for our Sept 6ht-14th trip to WDW. I know the ECVs come with a little shower cap thingy to cover the controls, if it rains. We have also bought us all good heavy duty ponchos to wear, plus an extra poncho to cover the ECV. What else do we need to do? Any more suggestions for keeping the ECV safe and dry? Will we still be able to tour in the rain is what I guess I am asking?
