Plat member here, I'm looking at booking a room at the Marriott Tokyo next year. I see a Marriott Rewards Advance Purchase Rate, and to me, an advance purchase rate means I pay the whole thing now, and that's it. No changes, no refunds.

However, when I look at the terms, that doesn't seem to be the case. It just says a credit card is needed to hold the room, and I can cancel up to one day before checkin, like your typical refundable rate. Screenshot attached of what I'm seeing.

So, what's the deal here? Is this a goof on the site?
