Hilton HHonors members can earn either double points or double miles when staying at participating properties.
The promotion covers stays completed between March 1 and May 31 and is valid at any participating Hilton Worldwide hotel. Click here for a list of hotels that are not taking part.
Members must first register at hhonors.com/double prior to check-out of their first eligible stay. If registering for double miles, members must select points and miles as their "double dip earning style".
When selecting either double points or double miles, members should note that their choice cannot be changed. Bonus Points earned on base points do not count towards tier qualification, and double miles are available only with participating airlines, a list of which can be found here.
