What I normally do is figure out first what park I plan to START the day at. Not saying we will stay there the whole day because normally we don't stay at one park the whole day. I use Touringplans.com for crowd calendars and tips on what parks to avoid each day. The people that do the statistics for the website also write The Unofficial Guide. Without a doubt, that is the best WDW guidebook and I use that in my planning as well.
I then decide what restaurants my family and I would like to eat at. I always pick two back-ups just in case something is totally booked up when I make my Advanced Dining Reservations. I then take a look at what park i'm going to on each day and match up the ADRs by location as best as I can. Finally, I call the ADR number and set up all of my dining. Sometimes I have to adjust my daily schedule if I have to book a dining reservation on a different day than I had planned. No biggie. It all evens out in the end.
It's time to whip out the planning binder now! I LOVE my binder. I organize it the same way each and every time I go. That thing never leaves my side until we get to WDW. Then it stays safely in the room and I only take one page with me to the parks which is in a plastic page protector. Yes, nerdy... I KNOW! But, it works! The page I take with me has our starting park for each day and the times and confirmation numbers to each ADR. This is what that page looks like...
After that I then make my own "park guides" with the dates, opening times, and any special happenings like parades and fireworks going on. I sometimes also make note of what parks to avoid each day. This stays in my binder so I can easily look at it before heading out to the parks. I know you can retrieve time and event guides at the parks but this is idiot proof to me.
I wish I had a picture of my binder all finished to show you but.. I don't. These photos were actually from our honeymoon when I did a trip report for Intercot. Doing this sort of this is truly where I shine. I'm good at this. I love the research end of it all. FUN FUN!
