The codes work on our Vistana account that has never been upgraded, as well. Interestingly, the codes continue to work on our personal II account even though I renewed over the phone yesterday. So another two years with a 50% discount, if I wanted to renew again today.This has been my experience also. Though I can't get them to work on our Marriott corporate account where Platinum expired back in June 2018. They will work on our Vistana account that has never been upgraded.
