If you have SPG points you can exchange them for free stays. If you have a friend or relative working at Starwood they get pretty deep discounts and can extend them to immediate family or friends. If non of those things apply you should call the 800 number for Westin and ask what kind of promos are available. There are tons of discounts that are never or rarely advertised. You can get a discount if you have
AAA or if you're over 60, if you stay for 3 nights many locations will give you a discount where you pay full price for the first night and get the next 2 for 40% off and it goes on and on. Many corporations have discounts with Starwood too. If you work for a big company like IBM or McDonalds and have employee ID you may qualify for a discount. If you work for the government and have government ID you may qualify too. Think about where you work and any memberships you may have and call in and see. You may be surprised.
