There are currently 2 online slot game promotions, one from Starwood (W, Westin, Le Meridien, etc.) and one from La Quinta; both give you chances to win points and/or free nights at their chains of hotels.
Take a Spin with SPG (through 2/7/14)
SPG game only allows for 2 spins per day, and the probability of winning is much smaller given it is a higher-end collection; however, you will be entered into drawings for free nights even if you do not win, and I have seen several friends win free nights from this game in recent weeks, so it doesn’t hurt to give it a try! Make sure to have your SPG number and e-mail address ready to play.
La Quinta Returns Stay and Play (through 1/31/2014)
This game lets you play based on “points”, which refresh each day; you can also go for the “bonus spin” which gives you extra points to play with. I have already accumulated about 5,000 points, a little short of the 6,000 points at which redemption begins for free nights. You can log in to the game via Facebook and watch your points rack up!
