Last year we stayed at Jambo in a 2BR lock off, just came back from Kidani 2 BR dedicated.
2 BR dedicated at Kidani was much larger than the 2BR lockoff at Jambo. At Kidani there were 3 bathrooms vs 2 at Jambo. The master bathroom was HUGE!!! I liked the set up of the rooms better there. The kitchen at Kidani was smaller than at Jambo, but there seemed to be a lot of unusable kitchen space at Jambo as it seemed more opened. With the dedicated vs. lock off, your balcony spans the length of your rooms, which makes it very long. With the lock off, of course the studio balcony is "locked off" from the main balcony. Also, there were two queenbeds in the dedicated 2nd bedroom vs the queen and pullout couch.
It can be a haul to go over to the Jambo house for a CS meal. But you can take any park bound bus and ride it to Jambo, and walk or take the DTD bus back to Kidani. A little hassle, but worth the bigger room in my opinion.
