I would like to try the Concierge and book the morning safari, and probably try the staff to get a few tough ADR's.
On the (-) side, you also have a 20% chance of getting the HA concierge room with no bath tub and I've heard the concierge food offerings have been really reduced in the afternoon/evening. If you are not booking the safari and you are expecting several food items in the afternoon and evening, and expecting an animal view, concierge may not be for you...
