So you're the one they keep the arcades open for!!

with all the games people have on their iDevices now, I always wonder why they still even have them!
Anyway, the 1BRs at Kidani are really nice. Not only do you get the extra room but also a second bathroom with tub/shower that you don't get in a 1BR at Jambo. Plus the master bath with the shower/hot tub is huge and your wife will love it when she takes it over like mine did.
Are you driving? If so, Kidani is also great with parking.
Otherwise, besides those two points above, to be honest, we do like Jambo more. But there are definitely positives to each.
The hallways at Kidani are super-long, insanely long. Think of the longest you can imagine. And then triple it. BUT, I think the standard views don't run the whole way, and that actually may be a benefit to you. They have a small snack shop in Kidani, but it's tiny. It's a good 10-15 minute walk from lobby to lobby over to Jambo. It's not at all quick to get over to the Mara QS, which we think is pretty good. But you're right, you can load up on snacks, cereal and milk (or even eggs and bread for toast) for the mornings, frozen pizzas, burritos, etc., that will make the 1BR differently convenient.
The pool at Jambo is huge, while the one at Kidani is relatively small, so we like the Jambo one much more, but everyone says the Kidani water slide is MUCH better. Can't speak to that first-hand. The bartender at the Kidani pool bar made better drinks than the one at Jambo the one time we tried each.
In terms of the animals, we've always booked Savannah view, but at Kidani they do have a big overlook you can go out to, plus the big community center room has an outside area with lots of chairs to sit out on and watch the animals. Plus those long hallways have break areas with benches and windows you can see out from. That might be good enough, but maybe others who have stayed Standard view can speak to this more. Whatever you chose, enjoy!
