I am a big fan of this site when I need to get answers direct from experts, but I would be lost without my other resources as well. On our first trip I subscribed to tourguidemike.com That reallly helped flesh out an outline. Also, I love the books : The Unofficial Guide to WDW and the passporter. All together those resources cost about 60 bucks.....a minor investment in a big vacation.
Our family finds that dining is a big part of our trips...the restraunts are as entertaining as some of the attractions! If that is of interest to you, the books I referenced will be a good start to choosing places. Good luck and don't hesitate to ask questions in the different forums here.
