We received our bid at 31 days out Regal Princess sailing out of Galveston for November 5th sailing.
BE to MB for $220 each, that was almost the max bid I think $230 was max.
there were at least 20 mini suites available to book still at the time our upgrade came thru.
i saw someone post in our FB group they won their bid so I checked mine showed expired status and about an hour later I got an email w/ a new cabin number and saw the charge come thru on my CC.
our friends also got their upgrade same day regular balcony to premium deluxe i dont remember how much the bid.
