Is she planning for one night or more than one night?
If only one night, best bet is to get on their mailing list or friend them on FB. Most of their codes (including their mailers) seem to be for multiple night stays, however emailed 24- and 48-hour sales sometimes will do one night.
Only code I'm seeing is Heroes... and you MUST have an EMT, military, fire department, etc. person in your party with ID to get that rate.
Otherwise maybe someone else here has a 2+ night code from a mailer, good luck!
