We are leaving today for WDW which will be followed by a trip on the Wonder. (Just sitting here waiting for our ride to the airport.)
By no means should anyone expect an upgrade. If anything, I think they'd give one to a cash customer ("guest") before us.
If you are looking for a cheaper way to be outside, I know my wife and I splurged on points this time to get a Navigator's Verandah. Not a full balcony view, but more economical.
