1) MK: Book it to one of the mountains (depends on what I'm feeling like for which I choose), ride it, grab a FP for it, and then go over to FL to ride the rides there. By the time I'm done with a few rides, I'm able to get another FP for a FL ride. (I average 6-8 FP, and have gotten up to 11 on my best day so I usually don't have to wait more than 20-30 min in the MK. I'm not a *stop and smell the roses* person especially in MK til the 12-3 o' clock corridor when it's most crowded. That's my chill time even when I'm in a park)
2) Epcot: This is probably the park where I'm most variable in what I do. Sometimes I've gone over to Soarin' (generally don't get a FP for it because I don't think it is *that* great. Once per trip is fine). More often than not, I'll go on Spaceship Earth just simply because it feels right and it is honestly my only *must* in the area since they destroyed Journey Into Imagination. But mornings are usually spent in FW before I chill in WS for the afternoons.
3) DHS: Go to TSM, get a FP, and then ride it immediately. After that ride, I go down to TOT, ride it twice, and by that time I'm usually able to get another FP for it for later. Ride RnR once via the single rider (seriously, I don't know why people wait so long for it when you can be on it in 5 minutes by single rider so my whole fam goes thru the SR line. We aren't paying attention to each other so much as the ride anyways). And then go ride TSM with my FP again. If line isn't long (unlikely but it happens), I'll ride it again. All the other rides in DHS generally don't have long waits/require FP so I slow my pace a little at that point. But that above is my formula for success in DHS. Can do that all in <2.5 hours if you like to move.
4) AK: Go directly back to the Safari. If you want to see the animals actually active and moving, morning is about the only time they are before it becomes too hot and they start lazing in the shade. They've just been fed and it's pretty great to see them so active. I actually tend to ride the safari twice before going on my merry way. I generally walk over to Everest to get a FP at this point though this is another ride with a single rider line so it isn't a big deal if I don't. I'll usually ride it once at that point too, if the wait isn't bad, though that varies. Most of the other rides/shows don't get too bad so I slow down after that too.
