The only one I can think of would be the Wilderness Back Trail Adventure Segway tour out at Fort Wilderness.
If you happen to be staying over at Animal Kingdom Lodge, they offer a Sunset Safari for guests staying at AKL. It's sort of expensive compared to the other tours, but it does not require park admission and includes dinner at Jiko. It was very good and I would do it again, if I ever stay at AKL again (they do check that you are currently staying there).
If you have to enter a park during any part of the tour, you have to have park admission. I believe all the other tours enter a park at some point. I've taken the Backstage Safari, Wild by Design, Around the World on a Segway, KTTK, Backstage Magic, and Yuletide Fantasy tours and all of those required park admission.
