This has been the only scenario where I was able to "use" these vouchers in the last 15 years. The hotels just couldn't be bothered and would usually just upgrade you to save time most of the time without even taking the voucher. I suspect even if you just approached the front desk and asked nicely without even mentioning the voucher, you would get an upgrade.
