I don't see the vouchers available anymore. They used to be available for redemption for Europe (and perhaps Middle East and Africa as well). There were breakfast and dinner vouchers.

Now, it looks like the options are limited to using the Any Hotel, Anywhere prepaid Amex (valid at any hotel worldwide that accepts Amex) or the Meeting Credits Amex (valid only at IHG hotels--but a cheaper redemption rate than Any Hotel, Anywhere).
