ProfMatt- Don't think lack of excitement will equate to lack of enjoyment! As another spreadsheet lover, planner, and analytical person, I just usually don't get giddy with excitement in general. In fact, since we did our trip right when school let out for the summer, I was more stressed than anything leading up to it. There was too much I was trying to catch up on at work prior to leaving, end-of-school year activities, sports tournaments, etc. that I didn't pack anything until the night before we left. However, once we were on the road and actually in WDW, all that planning paid off. Things went smoothly, and when we had to change things up, I was knowledgeable enough to be able to easily pivot. And even though when I was most excited was the night I actually booked the trip, I still enjoyed myself immensely while there, and was ready to book again while we were still on the road home.
The unsolicited advice I'd give is to try not to let your plans stress you while you're in the parks. We were there during some very high crowd levels, and I felt the need to keep moving on to the next ride so lines wouldn't get longer and mess up my plans but it sounds like you're going soon, and so you will definitely have a lot fewer people to contend with!
I've not been to Universal, so I don't have personal experience, but it sounds like you have planned it, just in a different way. WDW took brainpower, UOR took money. Either way, I'm sure it will translate to a smooth, fun experience. Once you're on your plane, relax and enjoy all your hard work!!
