AK is our favorite park. We always spend 2 days there. AK is not a thrill park. It is also "nahtazu" (not a zoo) It is a totally different adventure. It is the park to ease the stress and madness of the other parks. Everything is at a different pace here.
There are 2 wonderful walking trails (one through Africa, one through Asia) that are meant to be meandered through, not sprinted. The gorillas and the tigers are the big attractions on these trails, but there is so much to see other than them. Take time to enjoy the aviaries, the naked mole rat displays, watch the fruit bats, search for the other animals along the way.
We have easily spent over an hour at conservation station. Brushing the sheep and goats, watching a training session with the sheep and goats, watching the vets do exploratory surgery and check ups on the animals. We take time to search for the over 30 hidden Mickeys on the mural. The animal handlers sometimes bring out large snakes and other creepy crawlies to talk about and sometimes let children (and adults) touch.
We eat leisurely at either Flame Tree in one of the pavillions near the water or after the lunch hour at Tusker House. We enjoy the music and preforming artists throughout the parks. We take time to visit with the CM's who are from other countries and try to get in at least Tarzan Rocks and FOTLK.
Talk to the Animal Handlers throughout the parks. They are a wealth of information! Take time to enjoy the Oasis. Take a stroll (not a race) around the TOL just to look at all the animals. We've even gotten to the entrance of TTBAT and turned around and walked back out just so we could hunt for more animals.
Wonders of Flight is a fascinating show and the birds are magnificent! There are tons of photo ops throughout the park. I think the last time we were there we counted 8 different gods and goddesses from other religions in various forms. Stop and look at the ground. Although it is all concrete, it changes depending on what area you are in.
As for Dinoland, the boneyard is great fun for the kids (although some more seating for adults would be nice) and the carnival is supposed to resemble a roadside carnival that one would have found during the 1950's-60's in the upper midwest. From the appearance of things, it seems quite easy for kids to win things at the arcade booths. We have never played any of the games, but after we were explained what the theme was supposed to represent it made more sense. Dinoland is where we spend the least amount of time.
Oh and there is a safari ride to LOL!!!
But seriously, if you are looking for thrill rides, there are only 2 maybe 3 (Dinosaur, Kali, and Primeval Whirl) and the safari. If you enjoy seeing divers cultures, enjoying ambiance, noticing attention to detail, and soaking in the atmosphere you can easily spend quite some time at AK.
