O.K. - Calm down, everything will be ok. I PROMISE!!!!!

You have a couple of choices, you can look at easywdw for touring plans, or you can look at touringplans.com (you have to pay for this one)
Just look at the things you know your family will want to see, and check out the guide maps (you can see them online at Disney, or you can order them from disney for free) I personally do NOT go by a touring plan, we found the last 2 trips that we did better by getting to the parks at opening and getting everything done then taking our time for the rest of the day worked best for us. We also have the touringplans app on our phones (we paid for this) and the app is WONDERFUL for checking wait times, we also have the Disney mobile app and in comparing the 2 on our last trip, touringplans app was always closer to the correct wait time. The other really great thing about touringplans.com is that you can see the forcasted crowd levels - this is also on easywdw.com and they are different, but again, b\c we have the touringplan app we checked it everyday for the next couple of days (it has 10 days on the app) and it DID change a little while we were there (I felt it was very up to date also)
It is too early for me to start stressing over Disney - I just have to remember to breath. However, everyone freaking out, is making me freak out a little.
