Ask me again in March. I've stayed in a 1BR at Kidani twice, and have a 1BR at Jambo booked for March. In the 1BR at Kidani each time we had 4 adults (girls trip) and never felt cramped for space. We even joked that we could have added a few more friends on the trip! For that trip having 4 adult ladies, the 2 bathrooms was a must. For March it's the family. I chose Jambo over Kidani just for the location alone. I think with the kids along they'd enjoy the main lobby & all the activities at Jambo. They've stayed at Jambo before & love it. Plus, we eat at Boma several times a trip, so that will be more convenient staying at Jambo. So I'm sacrificing the extra space & extra bathroom for location. Sharing 1 bathroom isn't an issue, they're boys & are literally in & out of showers in 2-3 mintues.
If I absolutely had to choose one, I'd pick Kidani. It's soooo serene there, and I look forward to that after a long day in the parks. But I'd stay at either in a heartbeat. AKL is my favorite resort & I've stayed at most of them!
