Starwood Hotels -- Every 2nd Night 50% Off -- Sheraton, Westin, Meridien, Four Points, St. Regis and W Hotels

Here's another promo for the Starwood hotel chain (they still have the pay-the-amount-of-your-birth-year at some locations): every second night is 50% off. That means if you have a two-night stay, the second night is discounted. If you have a four-night stay, the second and fourth nights have the discount applied.

The offer is valid now through March 31st, 2009, and available at hotels throughout their chain. That includes hotels such as Sheraton, Westin, Meridien, Four Points, St. Regis and W. It looks like the promotion is valid at hotels around the world.

The 50% discount is applied to every second night and is based on the best available non-restricted rate. The Better Tomorrows rates are prepaid and non-refundable. See individual hotel listings for day of arrival restrictions and minimum lengths of stay.

If you like one of these hotel chains and have a multi-night stay, this might keep a few bucks in your pocket. You can book rooms online with promo code ZBT, or call 1-866-924-8703 and mention promo code ZBT. Here are details on the promotion.
