If I have two reservations can I bid only once through RoyalUp℠ and if accepted, cancel the second reservation and move the guests into the upgraded cabin?

No, if you have two cabins you will need to submit two separate bids and they will be considered independently. RCI cannot guarantee that both reservations will be upgraded. In the case that one of the reservations gets upgraded, you cannot move the other guests into the upgraded cabin. All reservations cancelled within the penalty period will be subject to cancellation fees.
