As others have said, it depends on when you go, length of stay, touring pace, etc. We just got back and being that it's Sept., a couple of our AK days after the am rush, we experienced wait times of just 30 for FoP (yes not available for MP), 10 for other attractions such as Safari. We did also RD so there was less of a need for LLs at AK, and usually we wouldn't buy them for AK even if we didn't RD... but that is because we generally have 7 nights or longer stays and multiple cracks where we can just do shows, trails, and select rides/greets on a busier day.
We did book LLMPs for our AK days, however, but only because we hopped to HS, once as early as 10am for a 10:20 SDD. We had a group of 10 so the savings by booking at AK over HS made more sense.
