Janny, I sent you a PM regarding your questions so as to not hi jack the thread. Hopefully you can use the answer.
Now to the OP. If you are moving to the Orlando area just to work for WDW, I would suggest you think seriously about if that is what you want to do. WDW rarely hires anyone for more than entry level work. Some higher positions are filled from outsiders but not very often since there are many CMs at the park who can qualify for them and who have Disney experience.
You don't say if you have any qualifications for specific jobs. Most in the tourism industry here are entry level. That doesn't mean all of them are, but you have lots of competition for those jobs from locals who are here to interview immediately rather than having to wait for someone to make travel arrangements down here.
As for the cost of living being high...that depends on where you are coming from. I moved down south from the Boston area...to me, the cost of living is lower than there. Apartment prices range depending on the area you live. Houses on the average are much cheaper than where I grew up. In fact, my sister lives in MA still and is paying over $450,000 for a new 3 bedroom house (being built). My staff assistant here just bought a new 4 bedroom house (built) from 180,000. And both are comparable areas. My sis is in a suburb of Boston...and my asst. is in a suburb of Orlando. So as I said, cost of living is relative to where you are moving from.
I would suggest if either of you have jobs now with national companies, check to see if there is the possibility of a transfer. I know a few people who have moved to the area that way. Or if you are in a field that is highly sought after in this area, such as nursing or education, then it might be easier to move.
Either way, good luck if you decide to go for it.
