I would not work there if I were you. Given your circumstances: kids, finances, new to the area, etc. I think that you should get a job that is going to pay the bills.
It's all glamorous in the beginning, but the magic does wear off. If you *really* want to love Disney as a whole for the rest of your life, then do not take this job. I speak from experience. I have seen the "behind the scene" stuff, and it has altered my outlook as a whole.
People go into the positions dreaming of the great "perks" offered to the employees. Sometimes those perks cannot over shadow the pay, hours, schedule, and everything else that comes along!
I'd REALLY REALLY think about your other alternatives before deciding to take this position.
And you had said something about getting a raise...I would not bank on it. JMHO.
