I kind of like ALL of the approaches mentioned above.
* If you have the points, book the entire reservation at your home resort at 11 months. This makes sure you have the whole reservation, if worse comes to worst.
* A couple of days later, try to book at least the First day or two of the second block right at the 11 month window. Get the whole second block, if you have the points, or as many days as you have points for.
* Now go and use the program to Modify your original reservation, cutting it to just the days that you plan to stay at your home resort. Because you now have the first day, or two, of the second block, as a separate reservation at your home resort. Modifying the original reservation will free up those points on the part that you drop from the reservation.
* If you didn't have the necessary points before, you should have them now, after cutting back on your first reservation. Now, go back to the second reservation and pick up the days you want.
You will now have two reservations, both at your home resort for the two blocks you want. When the 7 month window opens, go and use the Modify feature of the program to modify the second block and switch it to AKL or wherever. If what you want IS NOT available right at the 7 month window, then immediately request a Wait List for the exact days you want, and specify that they should replace the second block of the reservations. A lot of people may have reservations at their home resort priority window, but will be doing just what you are doing, and will be switching (sometimes over a period of days) to another resort. So, a Wait List put in early, should give you a good chance of getting what you want.
You WILL NOT be able to get a VALUE ROOM of any type at AKL at the 7 month windows. I'm not saying that something might not open up, but it is very unlikely. However, in the summer, you should have your choice of Standard and Savannah View Studios, One Bedrooms and Two Bedrooms, right at the 7 month window. But, be ready and start checking a few days before. Sometimes strange things happen. For instance, today, August 5th, there are no Savannah View Studios at Jambo, at the exact 7 month window. That day is gone. But they do have Standard view and all the other options at Jambo, and everything at Kidani. Weird.
Make sure to search both Jambo AND Kidani. Both are EXCELLENT, and Kidani has a ton of rooms available.
Jambo generally books out significantly faster, but you don't need Jambo by any means. Jambo has an amazing lobby, and it has Boma, and Jiko, which are excellent restaurants, and the Mara quick service restaurant, but other wise, it has NOTHING on Kidani.
Kidani is massive with more availability. I generally recommend that if you stay in Kidani, you request a room near the central lobby area, unless you prefer the Pool, or maybe a partial Savannah view of the Pembe Savannah on the north, or maybe the south end of the building so you can walk to Jambo. If you like walking. The shuttle runs back and forth every 10 minutes, and also all the buses that stop at Kidani go next to Jambo, so walking would just be because you want to. Kidani has an excellent kids pool, an excellent restaurant in its own right in Sanaa, and Sanaa also functions as a quick service restaurant for breakfast so you don't need to go to Jambo.
I have reservations for October in Jambo, for a two bedroom AND a studio, but I kind of prefer Kidani because the rooms are a bit bigger and have an extra bathroom in the two bedroom units. Whereas the 2 bedrooms in Jambo are Lock-Offs
I sent the email to MS and now have one reservation for a continuous stay at the BWV.
The walk between K and J is super easy - less than that upcoming VGF walk to MK.
