There are only 5 two bedroom lock off units in AKV concierge level. Two are on the pool view side, and three are on the savanna view side. Unfortunately, at least one of those on the savanna view side is handicapped accessible, so if you don't like HA rooms, your chances are pretty good you might get one when booking Concierge level.
The real draw for me with concierge level at AKV is the opportunity to book the sunrise and Waynama sarafis. An added bonus is the access to the concierge lounge where food and snacks and drinks appear throughout the day, and the concierge staff to book your dinner and show ressies, etc. Another little added benefit is nightly turn down service and daily housekeeping. Although, when we stayed there in March, we only actually got the turndown service once in 5 days.
