I understand where you're coming from. I get a burst of excitement when I have a formal "date" set and book the resort. I have another one at the 180 when I get my ADRs, and another at 60 when it's FPP time. But there's a lot of "ho hum" time in between. Then, a week or two before the actual start of the trip the excitement starts to build some. It ramps up again when I get in the car to start the drive, and by the time I'm driving through the gate, I pretty much in full excitement mode.
I enjoy the planning phase, but I'm not obsessive about it because I know that no matter how much I plan, things will change when I get there (and if you don't go with that attitude, then you will just stress out the whole time you are there). I make TPs because it's kind of a fun process, but the number of times I've followed one, as written, all day, I can count on one hand with fingers left over. I think the most important part of planning is not the sheet of paper you produce, but rather the research that you've done so when the unexpected happens (and happen it will) you can make educated "on the fly" changes and keep the day moving along.
Graphic design and layout is one of those things I "do". So, for the last "big" trip that my wife and I took, I created a very elaborate "tour booklet" (similar to the one you see in a travel agency for "see Europe in 10 days" tours). For each day I outlined which park we would be going to, what times we would be leaving the room and getting back, what some of the major attractions we would be doing, where we would be eating, etc. I also imbedded a few pictures for each day. A second section had a map of all of the parks and resorts that we would be visiting, and a third section had print-outs of sample menus for the (14) TS meals that we would have. I presented it to her two weeks before we left, along with the "reveal" that out last dinner there would be at the V&A Chef's Table. I had fun creating the book, and it helped her a lot to know what was in store for the next day (she has virtually no interest in the planning phase and trusts me to come up with the best plan).
