I haven’t stayed in a standard view at Jambo, but I’ve read that you should request a villa on the Kudu Trail to have the best chance of a partial savanna view.
Did you book with your own points, rent from an owner, or exchange in via II?
If it’s a points booking, the owner of the points needs to chat/email/call MS to make the request.
If you’re booked on an II exchange, you need to call DVC and tell them you’re coming on an inbound exchange. You’ll need to give them the names of all guests including infants. They’ll give you the Disney confirmation number for you to link the reservation to MDE, and you’ll need to link all guests to that reservation through your Friends & Family list, so that everyone can take advantage of benefits such as Deluxe Extra Evening Hours. You can also make your request for Kudu Trail when you call.
Have fun! I love AKV!
