Safari doesn't have single rider option and while lower rated than than Everest...it is probably the biggest reason a guest visits this park for the first time.
In all seriousness, what about Flights of Wonder? I have found it to be a great bird show especially compared to many zoos across America.
If you're not doing the Wild Africa Trek you might want to consider doing the Kilimanjaro Safari earlier in the day as the animals are at their most active before it gets hot and you will see far more than later on when they are largely sleeping...

If you are a ride fanatic you hit E.E and then move on working your way around the park.
If you are all about the show you hit up Nemo and then work your way counter clock-wards towards FOLK.
If you love animals then you hit Kilimanjaro Safari first thing (earlier the better cause there are more animal out in the open) and work clockwise though the park hitting the tails.
What EVERYONE misses out on is the 100% stellar performances put on by entertainment with the street entertainment. everyone walks by and never gives them a second thought
There is so much to see and do that is not specifically attraction based - Meander through the streets of Asia, taking lots of pictures, explore the trails around the TOL trying to spot as many animals as you can, sit in the shade near the water's edge and watch the monkeys (or turn around and watch the people), get splashed in one of the many "showers" positioned through out the park, study the beautiful architecture on Discovery Island, and listen to Guitar Dan make up songs on the fly.
Go slow - DAK is a steaming jungle that will suck the soft, air-conditioned life right out of you, but it's best enjoyed by going slow.
