I would study the resort maps and the frequently asked questions regarding room locations and try to get a room located across the hall from an open viewing location...then fax this is as a request.
You could always hope to get an upgrade to a pool view - some have posted that this happened for them. Or ask if there is any availability during your stay for a savannah view - it may cost more but it might not cost what it would have if you'd booked it from the start.
We are looking forward to our trip to AKL in May - now about those May hours....
take care,
LA
