$168 a night is a great deal for Savannah view. Standard view (also known as Parking Lot view) is fine, but there is a good reason it is discounted: it has a view of the parking lot. I will happily pay a little more to get the awesome savannah view. If you are on a really tight budget, booking the standard view in hopes of an upgrade could be a very good choice, but if the view is important, ensure it by booking the savannah view, especially at that price.
Note that it's a little bit less using the AP rate in January ($151, as I recall), but your $168 is very nice. AKL is by far our favorite resort. Enjoy!
