Taking Pictures In The Disneyland Resort For A Special Event?

I have seen pictures of people who have had their weddings at Disneyland and they are absolutely beautiful. The pictures take place mostly in front of the castle. They are professional taken pictures. I am interested in taking pictures there too, but i was wondering if this was possible without having an actual wedding there. I am having a Debut that is Disney themed so having pictures in front of the castle with the people in my court would compliment my theme quite well.
Although I’d love my party to be at the Disneyland resort, it is way beyond my budget.
Sooo,
Does anyone know whether or not i could do this?
Who do i get in contact with?
Any suggestions.
