If you change from one rate code to another, you are going to have to pay the prevailing rates. Don't know if the room credit would stay, though. And that's depending on where you booked as well. We booked through one agent a while back where ANY change of dates involved a cancellation and re-booking. We only book through Couples now because of that.
