Cabin Upgrade - Double Points Promo

[xtremegk]

I just upgraded my interior room booked during the Double Points promo to a balcony. I asked to make sure the booking # doesn't change, so I know, in theory, it shouldn't affect the double points. Is there anywhere on my invoice that I'd see that, though? My new invoice has the issue date for the date upgraded to the balcony, but the reservation number is unchanged.

You'll get the same points you would have originally received before changing your cabin.

Double points don't show on your invoice and never has.
