To move up or not to move up

 So the move up program gives you an opportunity to bid on a cabin in a class higher than the one you paid for.  You’re told “the minimum bid for this class is $$” and you decide how much you want to bid.   If your bid is accepted you move up to a cabin in that new class.  You don’t get to choose the cabin, but you get an upgrade at a bargain rate.  

This close to sailing, it’s easier for the cruise line to sell the cheapest cabins. So if you bid on a more expensive cabin and you move up, your less expensive cabin becomes available and can be sold to a last minute traveler.

We originally booked an ocean view cabin, and upgraded to a balcony when there was a price drop.   We decided we didn’t need to move up, we’re quite content with the cabin we chose.
