Depending on which suits your tastes better, you can select a room in one of those two styles.

Suite upgrade certificates are not accepted at the Savoy.

Room upgrade certificates are accepted.

Free night certificates are subject to capacity controls and are difficult to redeem.

If you managed to get to use your free night certificate, there's nothing preventing you from combining that with a Room upgrade certificate.

The Savoy officially allows you to book a Superior Queen room and upgrade into the Deluxe King. Or, you may book the Deluxe King and upgrade into the Luxury King.
