Just curious. Does anyone know if Hilton points will expire for Lifetime Diamonds? I cannot find anything on their website except for this:

Hilton HHonors points do not expire as long as members remain active in the program. To keep an account active, members can stay at one of Hilton Worldwide's hotels, or earn or redeem HHonors points within 12 months.

Surely, this does not apply to us Lifetime Diamonds.
