Not likely in Maui IMHO. The only suggestions I would make would be book as early as possible, with a cancellable rate if possible and then check regularly. Change if you find a better deal. Some people rate Costco but when I checked for Feb 2015 I found a better rate on Priceline ( although non cancellable).
I would agree with earlier posters though that a car , while not necessarily essential, would certainly be advisable if you plan seeing anywhere other than the resort, Lahaina and the Ka'anapali Beach/ Whaler's Village area. Apart from the shuttles mentioned the resort is a little isolated. If you're happy with those options then for a short trip you could get away without a car.
