Hi. This is absolutely the best kept secret in Florida! Well, now now, maybe. I loved this resort from the time I stepped foot in the lobby. It is breathtaking.
I stayed in a Deluxe savannah room. Yes it was on the fifth floor. We had about three feet more in length of the room. I could tell that the increase was the size of a balcony depth as I stood on my balcony and looked at the difference between the fourth floor rooms and fifth floor rooms. Our balconies stuck out further.
The view was amazing in the morning especially. When the animals would be called back and forth for feeding, etc, we could see them walking by. We had a lot of giraffs. They were amazing.
There are lots of places to view the animals if you don't have a savannah view, but I would recommend a savannah view if you can do it. I guess you can, as you are talking about concierge. Though we didn't stay concierge, a CM took us to see the concierge lounge. It is nice. It overlooks the whole lobby and view is across the lobby through the glass wall to the savannah.
Sorry I can't help more with concierge view rooms.
