I can only answer for myself -- AK, yes, HS, no.
HS is our least favorite park. But MK is next ahead of it (blasphemy, I know). Epcot and AK are where we spend the bulk of our time.
And just to throw that out there, this has been consistently true for the last six years, since my children were 1.5, 4.5, and 7. So I see all the posts about how Epcot may not be that interesting for those with small children, and the posts in this thread about the lack of rides for young children impacting the AK experience for families with younger kids -- but from a personal perspective, I don't get them.
