SkyMiles members who stay two or more consecutive nights at a Hilton family hotel can earn 1,000 Medallion Qualification Miles and 1,000 bonus SkyMiles for each two-night stay completed by May 31, 2008. You can earn the bonus miles an unlimited number of times during the promotion. Elite status starts at 25,000 miles so it would be difficult to sleep your way to the top with this promotion, but it could give you a head start to the benefits of SkyMiles Medallion status.

To ensure you receive the bonus miles, give your HHonors number and SkyMiles number when making reservations and at check-in.
