We have been offered 3 upsells.....once was on the Victory on a 3 day cruise when we booked an interior, and they offered for $10 more a day (so $30 total) to move to a balcony. I snagged that one. The other 2 I declined, one was to move us from a balcony to a suite, and the other was from a regular balcony to a spa balcony, but that was on a ship without the T-pool which is really the only spa perk I like.
