Members now have the chance to win one of four prizes by drawing virtual cards online — the catch is you’ll have to visit the SLS Las Vegas, one of Starwood’s new Tribute Portfolio properties during an eligible stay.For a limited time, SPG members will have the chance to win one these of four prizes:Earn 500 bonus Starpoints per stay (up to 1,500 Starpoints total)Earn 1,000 bonus Starpoints per stay (up to 3,000 Starpoints total)Earn two $25 Uber credits per stayEarn a night at any participating Category 1-6 hotelBonus points are one of the possible prizes you can win during Starwood’s latest promotion.The free night is most likely the best prize, although the Uber credit or bonus points might also be worth a trip if you’re already planning to visit the area. To take advantage of your prize, you’ll have to stay at the SLS Las Vegas by April 30, 2016 and be on an eligible stay — meaning you’d earn Starpoints for your visit. Luckily, stays at this property can be quite affordable with most rates hovering around the $100-mark.Since the free night can be used at a Starwood property up to a Category 6, this could be a great deal as notable Category 6 properties include Le Parker Méridien New York, The Westin Paris - Vendôme or The St. Regis Bangkok. Additionally, the Uber credits are also valuable — if you haven’t signed up for Uber yet, you can use promo code UberTPG to get $15 off your first ride.Keep in mind that you can also use the perks of the Starwood Preferred Guest® Credit Card from American Express to earn points toward free nights at other Starwood properties, like the Westin Austin Downtown in Texas, or The Great Northern London.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
