It works out pretty well if you hop to MK, and AK happens to be busy. Not as good as G+, but you still get to MK with 3 decent passes.
Though MP generally favors (adds value?) to hopping. It is not that I'm all that eager to hop, so much as MK tends to be open latest.
With each booked pass, MP gets significantly less useful- UNLESS you park hop.
When you hop, you start fresh in the 2nd park. Every available pass is yours to book. The longer you stay in your first park, the less valuable MP gets.
In AK, once you've picked Na'vi, Safari, and EE, that's it.
In Epcot, there's really only FEA, Remy, maybe Soarin' and maybe SE. Right now, FEA 60, Remy 50, Soarin' 30, and everything else is 15min or less.
HS is a bit of a mess.
Only MK has enough attractions to really make MP work.
Right now at 4pm:
Barnstormer 25/MP8
Buzz 25/ MP8
HM 45/MP 10pm
iasw 30/MP 6:25
JC 40
Aladdin 35/MP 7:40
Pooh 45
Pan 50
Pirates 35/MP8:40
SM 45/MP 10
LM 35
(the rest are 15min wait or less)
I usually swap over from the other parks to booking MK passes by 1pm, and it is now after 4pm, so I often get better times/choices than what I listed. On the other hand, I'm fairly certain that what I'm seeing is not quite what I'd actually be able to book, but 7 attractions still have worthwhile MP available.
But on days we start the day in MK, by 1pm, I have often already done much of the above. So then I'm only left with standby or only being able to book Dumbo (at about this time).
Mind, today is not a particularly great day to have bought LLPP IMO.
