HA! Yes, I remember that feeling. WDW turns you into a planning freak. Only after 3 big trips and a year with an AP did I finally learn to slow down with DL. There's really not much more for you to do this month other than post over hear on the nicer side of the DIS boards.
You really don't even have to get dining reservation right at 60 days. First, there's no
DDP so you don't have the masses rushing to get their money's worth. Second, other than Blue Bayou, there really isn't a place that stands out as an amazing TS meal. With good CS places at Plaza Inn, Village Haus (Kruat Dog!), French Market, Flo's V-8, and Pacific Wharf Cafe, you can do CS all trip without getting tired of burgers and nuggets. We usually do 1 or 2 TS per week-long trip. Way different than the 1 a day at WDW we used to do.
There's plenty that's changed since 15 years ago. For one, DCA (California Adventure) is an awesome park now. It wasn't back then. Definitely worth a few full days of touring. Cars Land is just amazing. And they have a nightly show called World of Color. You'll want to get FPs for that in the morning when you're there - located at the FP machines for Grizzly River Run.
Speaking of FP, it's the old style....THANK GOD!!! No uber planning each day. You show up, you head some place to ride, you grab a FP on the way, and just play it by ear...the way Disney should always be enjoyed. Sure, you have to do some criss-crossing, but DL is so small compared to MK that it won't be all that bad.
Be sure and enjoy the Nemo subs. It's like the old 20,000 Leagues subs but with a Finding Nemo theme. Also, Mr Toad still exists here so hit that for sure. I'm sure you hit these the last time you came, but there's some rides that either don't exist at WDW or are better at DL. They are Pirates of the Caribbean, Space Mt, Nemo Subs, Indiana Jones (like Dinosaur), Big Thunder Mt, Alice in Wonderland dark ride, Matterhorn, Small World, and lots of Star Wars stuff if your into that.
I'll leave you with this advice, which I know you won't be able to do because you're a WDW goer. But....take it easy and take it slow. Don't sweat it. It's a more relaxed vibe here.
