It goes through with an extra long link that I can't make sense of for all of its elements. No idea about cookies. However, once I've used the above link, as long as I keep the browser session active, I can open the Hilton side and enter the code manually and get the discounts applied. But all this may have to do with my browser settings or broken Hilton IT...
Having said that, it now works again on the best available rate w/o breakfast, the European properties I've checked now have 20% off the Advance Saver again.
