We stayed concierge at AKL in 2002. If you call the resort DIRECTLY and talk with someone at the concierge desk, you may should be able to get more specifics. They are supposed to help with your itinerary planning, etc. - that's what concierge is for. If they are not available, leave a message for them to call you back. When you talk to them, be VERY specific about your requests "IN ORDER OF IMPORTANCE" so they can do their utmost to fill them. If you want a view of the Savanah, you do NOT want to be on the very top floor (the one where the concierge desk and the food area are) as NONE of these have acceptable views - trust me, we made them let us look out the windows of what they considered the best views from that floor!
Personally, I am not sure why you are requesting concierge unless it is to take the Tuesday morning safari which requires a Monday night concierge stay. If that is the case, may I recommend you reserve a different room for all the other nites and stay concierge for JUST MONDAY night. I know that is a hassle with regard to packing/unpacking, but it can save you a LOT of money. We did not find the concierge of much benefit at the resort and honestly found the Savanah view better from about the 3rd/4th floors.
Keep in mind, we are a couple in our 50's traveling with no children so our perspective is surely different. Also, depending on when you are going, you may be able to book a standard room and easily be upgraded upon arrival if it is a slow season. -- Arriving late may be a different story, but still, call the RESORT directly for extra help/advice.
I loved the atmosphere, food, experience at this resort. Figured we will never get to Africa so this is the next best thing. The safari is really terrific and the breakfast at TUSKERS is absolutely splended. If you are a pin collecter, be sure to ask all the guides if they have and "CAST MEMBER" or other special pins to trade. These guides are not as frequently exposed to the general public and sometimes have some real treasures!
