I would like to modify an existing SPG reservation to add an additional night. The current number of points for a stay that length is exactly the same as the number of points needed to book the shorter reservation originally.


I am unsure if I should attempt to modify my reservation online as I don’t know if that process just adds the night or necessities a cancellation of existing reservation and subsequent rebooking.

Does anyone know offhand? I just thought I would ask before trying online modification or calling in.

Thanks
