As the article says, service is the best of the 4. Grandma can't move without someone offering to help her at the buffet or at the quick serve eateries. We've never experienced that at the same level on the other 3.
Lines not getting shorter, and I can vouch for that. Fri right after AK opened the line was all the way back to where you turn off the main walkway.
