I'm a first time cruiser and am in a Junior Suite on the Oasis April 5th. I received an email to "Royal Up" with options for a Grand Suite, 2 bed GS, Owner's Suite, Grand Loft Suite and Aquatheatre 1 bed! I thought our room looked lovely when I booked it but it sounds like there are many benefits to moving up in class; I put some time into selecting our location so I'm not sure I like the randomness of the upgrade too. How far out do they accept/decide on the bids if I decide to make one?
