As long as your new resale contract has the same use year as the first resale, your Kidani and Jambo contract will be in the same member number, can be combined for purposes of making a reservation starting at 11 months out at AKV Jambo or Kidani, and are combined for the the purposes of annual dues. However, when you go into the online reservation system, you will see AKV Jambo and AKV Kidani listed separately. You just need to make sure both are checked before attempting to view availability. Availability will then be shown separately for Jambo and Kidani, but once you have chosen one, both your AKV contracts will be available for making the reservation.
If your new resale contract is in a different use year from your original resale, then the rules are different. You will have two member numbers, and though both will be shown in the same online website (as long as the listed owners are the same), you are treated as two different members with annual dues charged and paid separately, and the contracts cannot be combined for any single reservation. To use both use years for one vacation, you need to either transfer points from one member use year to the other, or, alternatively, make two separate reservations, using one use year to reserve the first part and the other use year to reserve the second part, and then have MS link the reservations, which will assure you will not have to change rooms
