you definitely need to call and when you ask how many points for a harbor view also ask how many points for a towers room with and without harbor view. i would actually take a towers room without a harbor view as opposed to a harbor view non-towers first if the points are close. reasons being that with a towers room you have breakfast in the sky lounge with a fabulous harbor view and cocktails and snacks in the towers lounge also with a great view. in addition you get free internet and a laundry allowance.
