Registration is required. Every three stays through September 30 earns a free night valid December 19.
On the one hand, Starwood’s limiting the offer to two brands annoys somewhat, but presumably there will be a separate offer coming chain-wide shortly. And the earning period for these is fairly short.
But it’s nice to see Starwood giving away free nights, and not just free weekend nights. Maybe they’ll learn from Hyatt yet!
