We rented one in June. If the doors swing out, you'll need to pay attention to how close the car beside you parks at the theme park parking lots.
I can't remember which park it was but a jeep pulled up super close and there was no way we were getting the kids out! So, I asked the lady if she could please adjust her car over in the space more! She knew she was way too close when she went to open her door and could barely squeeze herself out.
At the Animal Kingdom the parking attendant saw us and directed us to the last spot in the row right by the tram, that was really nice of him.
At the resort there were a few spots that had wider areas beside of them for the maintenance people. My husband always backed in to those with no problem. If those weren't open then he would just go a little farther out in the parking lot where there were more empty spaces.
