My request was processed within 24 hrs and company code (customer code) and access code generated that can be manually entered into the search or better, add them via “Work details” under your profile (I found the app easier to do that than website).
I immediately saved $40 by rebooking one night next week in the UK. Which is significantly more than the advertised 5% for an Ibis. Not sure how but not complaining.
Alas, a future booking in CBR later in September didn’t have discount nights…
I’ve not had a chance to play too much with properties, days rates etc But some random searches appear to show different discounts to different room rates on different days - if that makes sense. So it could be hit and miss on some properties.
