Thank you Island, your reply clears up at least some of the confusion. You're always so helpful, I hope you'll get lots of reputation squares very soon!

Now, can anyone explain how these pre-paid rates work in terms of cancellations? The rate is described as a pre-paid Websaver, but in the booking page it's mentioned that cancellation must happen by 6pm day of arrival?

Oh, and I can't easily call Rewards Network and ask them because I'm currently overseas.
