We stayed concierge on points in Sept 08. We did get nightly turn down service. We also paid to do the sunrise safari, which is at AK and includes breakfast.
They have a lounge area that gives you breakfast (cereal, fruit, yogurt, danishes), afternoon snack (cookies and drinks), evening appetizers, desserts, cordials (apps & desserts are from Boma and Jiko; cordials were several options of alcoholic beverages).
They had drinks available all day. There was a small refrigerator in there. If they were out of something, you could ask and the CMs were very helpful. My dh asked for coke in the morning and they were given to him. I also asked for zebra domes one night and they brought me some.
There is also a sunset safari that is right there at the lodge. Very limited in the amount of people they book and I think no one under 8 or 9 are allowed. It includes dinner at Jiko's.
