There is a car rental center about two miles from the Grand Floridian, Poly, and transportation center area. You can't walk there to pick-up a car due to all the construction and highways but they will come and get you. I rented a car for one day in October to drive to Mount Dora about 50 minutes from WDW. It was just over $100.00 and was a small car. I am frugal but could find nothing else. (I will not Uber that far.) I did not keep the car over night as I did not want to pay the resort parking fee. (We rented a car from there a couple years ago to go to the grocery as we had a full kitchen etc. However, we now use Aldi delivery and it works great. Never have gone to Aldi's at home but do now as they have been so great on our Disney vacas.)
