Received notification yesterday afternoon that one of our bids won! Exactly three days before sailing. We were pretty surprised since we bid at the very bottom.
Sailing on the Joy, original Cabin was Haven Suite, HJ category. Won Fwd Penthouse, HG category. For us this is great as we gain a living room, larger bathroom (with separate tub & the nice showers we love), but we'll sacrifice the mid-ship location and larger balcony. Here are the details I think most people are interested in:
Our bids were all about $10 to $15 higher than very minimum: Bid $615pp for 2 Bdrm, $515pp on Aft Facing PH, and $350pp on Fwd Facing PH (this is what we won). Unfortunately I don't remember what the high/excellent big cap was. Direct upgrade for the rooms we bid on were approximately $2k to $2.5k per person more than what we originally paid. Interestingly, mock bookings this week showed 12 2-Bdrm Havens, and one Aft available, so I'm guessing people in Fwd cabins may have scored the larger staterooms with higher bids. Who knows how the algorithm works!
Hope this helps and good luck to those waiting for upgrades!
