(1) 150,000 points for 7 night(s)
(2) Points Advance: wait until you earn the points you need

I do not see where I am able to attach the certificate. Now, I have never used one in the past so may be it is just user error on my part but the Marriott agent said that this is the part of the booking process where I should be able to opt to apply the certificate. Was she right? If not, can you please point me in the right direction? Thanks in advance.
