What do you need to become a DISNEYLAND PHOTOPASS PHOTOGRAPHER?

Hi I'm 17 years old still in high school as a junior. I don't graduate high school till I'm 19. Do you need a high school diploma for this job? My dream is to become a photopass photographer at Disneyland and my oldest sister has been working at disneyland for 3 years now and she can get me a job. I have a Nikon D50 at home that i carry it around with me everywhere because i love photography and my photos come out really well. I was wondering if you have to have a degree in photography as a "professional" photographer for disneyland, or could i just show up with a portfolio of my photography pictures? Also, how old do you have to be to work as a photopass photographer at Disneyland? My sister says 18, but I also read online that sometimes you have to be a certain age to work in a specific job around Disneyland. Please HLEP.

Well, I happen to know that Photopass photographer is one of the options for the Disney College program, which is an internship you can do during college.So, people without college degrees work in the park.
18 is the minimum age, but there's a chance they prefer to hire older people.

Also, don't bank to much on your sister, she can put a good word in for you, but I doubt she can directly hire you.
