Waitlists work also. I booked a standard studio x 2 and waitlisted for value studios- not one but BOTH of my waitlists came through.
I didn’t receive an email or anything, so I don’t know when they were filled. I just happened to log on and saw I had more points than I thought I should. Checked- and was surprised they both were filled.
I was able to book 2 value studios at a month and a half out once…of course it was right after they released the rooms just after reopening in July 2020, so I guess it was kind of cheating. I got a savanna view, hope you get lucky and get one too!
The Riviera ones you're thinking of (2-person rooms with a murphy bed) are called Tower Studios. Not a "value" as I think they're nearly as many points as an AKV savannah-view studio.
The Value studio category at AKV is a significantly lower-points room and hard to get.
