Citi® offers a premium level of benefits when you upgrade your existing credit card two a more valuable or Elite status credit card. You may have received an invitation number for the Citi® Hilton HhonorsTM Visa® credit card with an offer to upgrade to the Citi Hilton Hhonors Reserve card which comes with enhanced benefits like a bonus one weekend certificate.
If you spend more than $40,000 in a calendar year, they will upgrade you to Diamond status. By upgrading to the reserve card you can get 10 bonus points for every dollar you spend on hotel stays within the HiltonTM portfolio, 5 bonus points for every dollar spent on Airline and car rental purchases as well as three bonus points for every other purchase.
These benefits do come with a price though, a $95 annual fee, but this can easily pay for itself if you have the ability to spend a substantial amount during the year.
