Just an FYI, I had a Club Balcony room on the Joy for Dec 18th cruise to Mexico and bid on nearly everything Haven... all in the mid tear of bids... Then last minute when I saw that they were discounting the Penthouse Suite with Balcony (SC) rooms. I knew they were not Haven, nor had many perks other then a larger room so I threw a low ball bid on there of the minimum, and 2 days later I got the bid.
When I looked there where very few Haven rooms left so that motivated me to bid on the non haven upgrade, and it worked.. or back fired.. I'll never know... but We did get an upgrade, and we will enjoy or short jaunt down to Cabo and back 🙂
