Starwood Preferred Guest: Earn a free Weekend night every time you complete 5 nights at Sheraton hotels Worldwide

A few weeks ago Starwood gave some teaser information on FlyerTalk and
Milepoint about this promotion and now SPG has released all the details
of the offer other than actually being able to register for it.
Registration doesn’t start until July 9th but you can actually book
stays for the promotional period already. The offer is quite simple,
complete 5 nights at Sheraton Hotels Worldwide and get a free Weekend
night, up to three times. Like most free night offers there is a limited
window that you can use them and that is until December 14th with this
promotion. Hotels like these kind of promotions as they provide higher
breakage than points offers since there is an actual expiry date on the
bonus being provided. That being said, it is a pretty sweet deal as the
free nights can be redeemed for any participating Sheraton Category 1–7
hotel for a
standard room for any weekend night (Friday, Saturday, Sunday except in
the Middle East, where it is Thursday, Friday, Saturday).  As you can
see there are no limitations on the Category redeemed for so if you can
make each of your 5 paid nights at lower priced Sheraton’s you can
really max out the offer by using the free night(s) at a Category 7
hotel, which unfortunately there is only one but Cat 6 had seven hotels. On top of that this promotion can be combined with the current
SPG systemwide offer Make it Count
which awards 1,000 Bonus Starpoints for stays of 2 or more nights that
includes a weekend night at all Starwood Hotels Worldwide.

Offer Details:

Earn a free Weekend night every time you complete 5 nights at Sheraton hotels Worldwide. Maximum of 3 free nights awarded.  Full details, online registration and booking (Registration is required) Register by Sep 15 for stays Jul 9 – Sep 30, 15

(Award nights can be used separately or combined and redeemed
for any Friday, Saturday or Sunday nights through December 13, 2015, at
