Is Disneyland done hiring for the summer?

I am going in to apply to the Disneyland resort (in Anaheim) this Tuesday. I am a graduating senior in high school, and want to work at Disneyland from June to September until I start college. My question is: is Disneyland done hiring for the summer? Or can I apply this Tuesday, and still have a chance of getting hired? It is my dream to work there, but please be honest with me! Thanks :)
