It's my understanding that most RCI exchanges into AKV (but not all) have historically been savannah view. I believe there is a way to find out online through RCI if you want to search previous threads (I think it was in the sightings forum).
I exchanged into AKV once and confirmed the villa view through the RCI phone customer service by asking about the room code. It was something like SAT1SAV (may have been in a different order... basically, a combo of letters for checkin date (Saturday), unit type (1 bed villa), and view (Savannah).) I ended up switching that match for a BLT unit. When I called RCI that time, the customer service representative was unable to tell me the view, so instead I called DVC and confirmed it was a lake view villa. View was important to me because we were trying to cobble together a 2 bed lock off by booking a 1 bed through RCI and a studio through DVC (obviously views on both needed to be the same in order to connect)
Unlike using DVC points, there isn't a way to specify which view you are looking for on RCI. Although most AKV matches have historically been savannah views, I have seen some Standard views lately.
good luck
