I have just completed a 5 night stay in London. I paid for the stay on points, but paid £65 per night for an upgrade.
When my points were credited, I have only received them on the extras, not the £325 upgrade cost. Why? This makes no sense to me. If I had booked a standard room not using points, at say £185 per night, I would have got points on £925. If I had booked an executive room at £250 per night, I would have received points on £1,250. So why don't I get the points, which amount to approx 4,000, on the cash upgrade cost? After all, my points only paid for the standard room.
My bill shows the £65 each night as "Rewards Redemptions" but it is not a rewards redemption at all. It is a cash cost in addition to the points I used.
