Have confirmed that the two standard GVs are those at the end of the north wing. They also provided the reason for making them standard. That is near the gate where the animals enter and leave the savannas (the fence referred to above). and other than when they are entering or leaving the animals are not really in that area during the day. Each savanna is closed at different times for two hours each day and the animals actually go off savanna for cleaning and care through that gate when a particular savanna is closed and that is likely the only time guests in those GVs will see them.
