If you dont have time to read it, I dont think it would help you much. If you only have an hour, it may just confuse or panic you more than it would help (maybe, not sure, but maybe).
If you can dedicate 4or 5 hrs to the site-- I would get it, hop right on their forums and say here is the situation. I think everyone would help you to pull up the most important articles to read before you go, and it would be well worth your time (MHO)
The super express planner is made for those who only have limited time, a couple of hours-- you could just print that, and read it on your way down to Disney (assuming you are not personally driving).
