Where to start??

[sablebomb]

This is my first time even attempting to plan a Disney vacation.

Where do I start?

We have narrowed down a date (January 2014) but that's about it.

I guess first choice would be to decide if we want to stay on site or off site?
Any suggestions? I've been sent some great links to different places and talked to a few people who have done both and I guess both have thier benefits.

Then what?

And, I must ask, ball park figure, for a family of four (two adults, two kids) approx. 1-2 weeks, how much of a budget should we be looking at?
