It appears that the Hilton rep on Flyertalk.com has issued an invite to match your status in another scheme, to HHonors.
Hilton is not as lucrative as Hyatt – no suite upgrades for example. In truth Gold level status is easy to secure – they run promos, credit cards off it etc. Diamond doesn’t offer a great deal more than Gold – but does give you lounge access even if you do not get a room on the Executive Floor. (Gold doesn’t let you in the lounge unless they upgrade you, but there are plenty of reports that they do make exceptions especially in Europe).
Here is the FT post if you’d like to snag another elite status in the same week.
