We booked Ali Kai through RCI a number of years ago. As you said we booked Ali Kai but units were actually in Ali Kai II. I believe Ali Kai is primarily private owned condos unless that has changed.
To add to the confusion different units are owned by different associations. At the time of our exchange we were in a Shell vacation club.
I believe they did a major refurb not long ago and units could be very nice depending on placement. We enjoyed location and unit size was great. I would not count on much of an ocean view. We had a limited view between buildings.
If it is the same as before you can count on lots of chickens and other birds
I would definitely return.
