I have the same question as the OP regarding a room in Waikiki. I do not understand the link, I guess, as it did not answer my question about what an upgrade certificate is! Should I have some of these certificates in my account? I'm gold level.

If what Marriott wants is more points to upgrade, why don't they just say so! Calling addition points required to upgrade makes it very confusing. The room I'd like is 105,000 points plus 2 (I think I recall correctly) upgrade certificates. If those certificates are actually miles, why not say so!
