What time of year and what size room are you thinking of (studio, one bedroom, savanna view or standard view). Prices vary for time of year. A quick check showed a low of $570 and a high of over $900 per night.
Animal Kingdom Concierge is also one of the harder rooms to book especially Studio, have you tried calling Disney to see availability options as you may spend a lot of time looking and find you cannot book the room you want.
