@Nnilak,
People have made good points about money (I live in California and everything is expensive, so my mind always wonders where the next dollar for the bills are coming from,) but honestly, this is your life. If this is what you're feeling called to do, go for it! Listen to your heart! Even if it's only for a year or so, at least you took a chance and stayed true to yourself and your dreams.
If you want to move closer to WDW, do it. Apply for a job there, or in the area so that you will always be near!
The plus side to trying to work there are the benefits. Free entry for you (save for special days where you're blocked out. I think you get blocked out about 15 days of the year, but that's it,) 20-35% discounts, a whole slew of 'real world' discounts, including apartments and housing, plus you have options for medical.
Should you work elsewhere, consider getting an annual pass. I've have one for 19 consecutive years, and I live about 40 minutes from Disneyland CA on a good traffic day. Granted, all my entertainment money for the year goes to Disney, and my house is littered with Disney merch. I don't have cable and I don't see many movies, and apart from Internet, Netlfix and books from half.com, I really don't buy too much to entertain myself. However, when my family and I just want to go have some fun, we go to Disneyland. There's parking on my pass, and we can stay for as long as we want. Sometimes we go in for 4 hours in the morning, and leave when it gets hot, or go in for the fireworks in the evening.
If Disney is your passion, and you just want to be around your fav park, I say go for it. You're not ridiculous, you're not childish, you're not being unrealistic, or whatever anyone else will say to try to stop you. You can forge a path in any location. What matters most is if you're happy, because if you're happy, then those around you are happy, and your boss is happy because you're working hard to be able to go have more fun after work!
