We always rope drop when possible, but our kids are teens, and we actually skip a lot of the more popular rides...like Frozen, SDMT, and Navi. So i won't include those, BUT if you do want to ride any of those, I'd put Frozen and SDMT at the very top of the rope drop lists. Navi after FoP. We often skip all of Fantasyland too, so we also leave off Peter Pan, Lately though, PP waits are not too bad.
AK 1st day: FoP, Safari, EE (morning safaris are the BEST.)
AK 2nd day: FoP (if you loved it,) OR EE, Dinosaur (then Kali and Safari again)
MK 1st day: Space, Astro Orbiter (kids love this...), HM
MK 2nd day: BTMRR, Splash (multiple rides on both if possible,) Pirates or HM (or Jungle Cruise if you like it)
Again, if you want Seven dwarves Mine train, do it first! on the 1st day!
Epcot: 1st day: TT (often not quite running at opening,) Mission Space, Soarin
Epcot: 2nd day: Soarin, whatever you liked/missed. OR Frozen if you want it, and do it 1st!
HS: SDD, MFSR, ?? maybe MMRR if line is not long, or a lot depends on your RotR BG
HS: ToT, RnRC, MFSR, OR if you want to ride MMRR (which is SO great and fun) do it at rope drop.
We had luck having the times go down after lunch, and right before closing. But definitely get in a ride on MMRR, it's a great addition
Could change, but we found Slinky times stayed high most of the day, I'd rope drop it. TSM was kinda low a lot of the day. MFSR varied. MMRR varied. Queue is mostly outside, so prepare for that. Night was better for it for us
Good luck!
Keep in mind parks are opening quite a bit before actual scheduled time. Rope drop for us means being at the park at least an hour before opening. Hubby and son were 2nd on FoP one day, and first on ToT another day.
