All parts of the Jambo 2BR will be smaller than the Kidani 2BR. The Jambo room is close in size, about 1070 sq ft, to 2BRs at BCV, VWL, BWV, and SSR. The Kidani 2BR is about 100 sq ft larger with the living room being significantly larger and the bedrooms somewhat larger. The master bath at Jambo has a combined tub/shower and it is a large step over to get into the tub, Kidani has the separate tub and shower. It has the extra bathroom and you can get dedicated 2BRs with the second bed rather than a couch bed in the second bedroom. Kidani also has more closet space and the master bedroom closet is an attached to the wall unit while at Jambo it is a free standing closet that takes up too much room in the master bedroom.
I am one those who believe the Jambo pool is better (lots more shady areas for adults), as is having the three restaurants and the larger lobby and store, but if I am getting a 1BR or 2BR there Kidani wins every time.
