I just found this out today when I went to the Food and Wine Festival, I am a seasonal passholder and now will have to figure out if it is worth it for me to spend the extra for a regular annual pass, since I too stay onsite several times a year I know I wouldn't be paying for parking then, and since I never go in the summer I almost think I will still be farther ahead staying with the seasonal pass. I really think it is getting out of hand with the parking fees everywhere not just Disney.
