Did you book an interior (no windows in the room) guarantee? If there are unsold cabins on a higher deck, then you have a fair chance of an upgrade. If you are really concerned, You could probably pay for an upgrade now, and you would have a better selection to choose from. Lots of people get nice upgrades with a guarantee booking, I just never have gotten lucky on them.
However, let me tell you, there are NO "bad" cabins on the Conquest. Every interior cabin is exactly like any other interior cabin. The only difference is, of course, the location. I agree with Hubby... just get me on the boat! I really do not mind climbing extra stairs if I saved enough money on the ticket to be able to splurge a little elsewhere.
When we went on the Conquest, we booked on one of the "One Day Sales", and got upgraded several decks higher than what we paid for. This may be something you could look for on your next booking.
As you cruise more and more, you will begin to decide what location on a ship works best for you. If you need to be higher up on the ship, or if you must have a window or balcony, then you are just gonna have to talk sweet to hubby, and bat those beautiful eyes a little more!:lol
