Welcome to the boards OP.
So my tips.
1) know how you travel. while there is a ton of advice, the problem because if you try to "force" those tips to your travel style. for example, most people here advise getting to the parks at rope drop, and it is a good piece of advice IF your family likes getting up.
My family hates it and the year I forced my dh and kids up for rope drop our trip was a disaster.
2) take your time. Disney is expensive (especially park tickets) so some times that makes people try to "do it all". there is no way to "do it all".
3) pick up a good tour book. while I love the dis, I find I some times I like information without the opinions to "sway" me.
4) Now this is my one criticism of the mouse world and it depends on how much of a foodie you are.
I am not a fan of Disney restaurants, IMO they are ridiculously expensive, the food is very mediocre, seriously over hyped and I hate making reservations 6 months out. Unless you go to the signature restaurants it will be hard to get a TS meal that I would call great. I've been going to the world for 20 plus years and the restaurants have nose dived to the point where I rarely eat on site. I hate wasting time on a meal and then leaving feeling like themeal was just "meh"
So my suggestions would be to split it. If you want some really good meals, pick off site restaurants. then try a couple of character meals or quick service places.
LOL this is just my opinion, go back to rule 3
