Andreko,
That is a big question, even if it is just a small sentence. The best way for you to get a more direct answer would be to contact a Disney Authorized Vacation Planner (like Mouse Fan Travel, or Dreams Unlimited) that is a no-fee agency and have them quote it out for you based on a few items;
- When will you visit?
- How long will you stay?
- How many days of that stay would you plan on going to a theme park?
- Where would you like to stay?
With these basic questions answered, they can quote you resorts from all classes, ranging from deluxe to value. You can also stay off property, which can change the price.
I would suggest that with younger kids you can stick to standard tickets, and you don't need the extra ticket options. From there, let the quote for whichever resort best matches what you can afford drive where you stay, and for how long!
So that should get you started. Write me back if you have any follow-up questions!
Have a magical vacation!
