I have posted this so many times before in so many different places, but I always get the same response from those of us that have stayed multiple times at both. Usually, something akin to, "Spot on." (Under NORMAL times and circumstances which Jambo House most certainly is NOT right now. Not in the least.)
Jambo House is a hustling and bustling 5 star resort with 4 and 5 star restaurants encapsulating a captivating and large, well-sclupted pool and an African savannah just out your window. Probably the only resort at WDW that could stand fully alone as a vacation destination, and do well, outside the boundaries of the Disney bubble that is southwestern Orlando.
Kidani is home. Quiet and peaceful, like home. Home, that just so happens to be on an African savannah. On your back porch. And just a 5 minute casual stroll (for us, at least) or van ride to all of the above.
Pick your poison. We'll be at Kidani starting tomorrow. I have literally lost count of the number of times. It's home, and it feels like it to us. We can't wait.
BTW, right now we plan to be at Jambo for Easter, but that's all contingent on the state of Jambo as we move forward. Right now, there is zero incentive to stay there over Kidani. To us, staying there would be a disadvantage right now. We walked over several times during our August trip, and I gotta tell you. It was eerie. That's the only courteous way I know to describe it.
