We rented a car in June and was able to show our room key to the front gates and was able to get in without paying. Infact, when we decided to resort hop one day, all we did was show are room key at the gate and they just waved us in, didn't have to worry about giving them a reason why we were there. I love Disney transportation, but I thought that taking our rental car all around was the smartest move for us since we have 2 young kids.
