As a former art director, I get much more out of AK than the other parks. The detail that has gone into planning and execution, from the different textures and impressions in the paving to the tangles of wires in the Asia section is amazing. Just piecing together the backstory of the memos scattered around Dinoland will prove how in depth was every move made by the Imagineers.
The McDonald's (or substitute burger joint now) in that section is probably my favorite building in the United States (including Fallingwater, sorry FLW), with the flawless transition between Quonset Hut garage, Airstream Diner, National Park lodge and Forestry service bivouac - completely filled with artifacts tied into the backstory(o'saurus). A collection of Star Spangled War Stories comics in the trading post inspired me to collect a complete series.
The signage everywhere is fantastic, especially the beautiful banner for Flights of Wonder. At Christmas, every shop has unique and inventive garlands with elements relating to the store.
The live shows are great, the plants are incredible, the food is actually good and the bars are the best in Disney. It's the largest park, the most natural park, and the park with the most detail if you have the eyes to see. Many, many hidden wonders here.
And, yeah - there are some animals and rides.
If you're not into all that detail and fantasy, why bother with Disney at all? I'm sure there's a game on TV
