In most cases, going to a King Room is considered an Upgrade, not a Downgrade.
The King room we had at the Swan was a Jr. Suite - Very Luxe, tons of room, with a gorgeous Heavenly King Bed, a pullout sofa (all we had to move was a coffee table) a dining Area, a desk area along the wall, balcony, windows on 3 walls & the bathroom/vestibul.
