We are attempting the same upgrade bids from a club balcony "suite" w/large balcony to the Haven for a 8/14 trip on the Joy. Not sure if it's worth it or not, but want to try.... No bids outside the "fair" category yet. We like the room we already have so not going to be disappointed if we don't get it. Bidding on all Haven room types just to try to get into one (some categories are sold out).
