Do this now: Starwood Preferred Guest early summer promotion
/Between May 1 and July 31, 2014, Starwood Preferred Guest is running a promotion giving double base points at participating properties for stays that don’t include a Sunday night (Saturday night in the Middle East) and triple base points at participating properties for stays that do include such a night.
There’s a long list of non-participating properties, so don’t deliberately direct any stays to Starwood properties without making sure the property is participating in this promotion.
And of course, register now, before you forget.
