It probably depends on how much time you plan to spend at the resort (and it sounds like not that much). If you're staying on the Kidani side, you can easily walk to Jambo for the restaurants (Boma, Jiko, The Mara are at Jambo) and the souvenir shop. Sanaa is at Kidani. Rooms on both sides are very nice - we actually prefer the rooms at Kidani slightly.
The buses at AKL work pretty well, with only 2 stops - 1 at Kidani and 1 at Jambo House. The only longer bus ride is the one to Magic Kingdom - if that's a park you plan to do. The other parks aren't that long of a ride. But I wouldn't recommend an Uber to Magic Kingdom, as you get dropped off at the Ticket & Trans Center, and then need to boat or monorail the rest. Not sure if any of this helps, but enjoy your stay!
