Thoughts..
First off, are you in the hospitality field now? If not, you should start working in it, in your area to get an idea.
I have been in hotels for 24+ years (from line level to exec management). It is a ton of hours and work. Remember you work when everyone else is off. You will work nights, weekends, holidays etc.
The pay is not great to start. Sure I make great money now, but it was a long road and you have to fight to stay "on top". In our field it is easy to know if you are doing well. There are many measurables you have to hit. From profit, customer satisfaction, turnover etc.
I love what I do. But I have seen a ton of people come into it and burn out in a hurry.
Also Disney pays less then the industry standards, so keep that in mind. My understanding is the cost of living in the Orlando area is higher so that is a tough combo.
I have seen couples that retire and go to Disney to work part time and that seems to work out well. Keeps them busy, Disney gets reliable help and they get an ok wage to supplement retirement.
But to move there and make a career out of Disney without having time in the industry would be a bold move. It would mean uprooting your family. Plus remember there are layoffs all the time in hotels and you might find youself working for Marriott in 4 years and driving by Disney instead.
I vote for staying where you like, with family around you once you have kids. Prior to kids, my wife and I moved everywhere we could with my job. Since it was only us, it was great seeing parts of the country and opening hotels. But once we had kids, we moved back home ASAP and I never looked back.
