I bolded one sentence that is good news. Read the terms and conditions here:
The Big Night Giveaway Promotion ("Promotion") is available only to Club CarlsonSM members for new reservations. To be eligible for the Promotion, members must register online for the Promotion at
http://www.radissonbignightgiveaway.com ("Registration"), provide their Club Carlson member number at the time of reservation or check-in, and then complete one Qualifying Stay at any participating Radisson® or Radisson Blu hotel in the United States, Canada, or the Caribbean ("Participating Hotels"). The Qualifying Stay must begin on or after November 10, 2011 and be completed by December 30, 2011 ("Promotion Period"). A "Qualifying Stay" is defined as a stay of one or more consecutive nights through the Promotion Period, for which the guest specifically booked a rate for which Gold Points are awarded in accordance with the Club Carlson Eligible rate Terms and Conditions. Guest must be enrolled in Club Carlson and registered in the Promotion at the time of check-out (to enroll in Club Carlson, visit
www.clubcarlson.com). The first 50,000 guests who complete the Promotion Registration will receive 50,000 Bonus Gold Points after the completion of the Qualifying Stay. Every guest who completes the Promotion Registration after the first 50,000 registrations will receive 15,000 Bonus Gold Points after the completion of the Qualifying Stay.
These Bonus Gold Points are in addition to the standard Gold Points awarded for a regular stay. Only one Club Carlson account per Qualifying Stay will be credited with the Bonus Gold Points. Maximum of one Bonus Gold Point award will be credited to a member with a Qualifying Stay under the Promotion regardless of the number of Qualifying Stays completed by the member during the Promotion Period. Allow 6-8 weeks for the Bonus Gold Points to appear on account. The Promotion and Gold Points are subject to all Club Carlson program Terms and Conditions. Rates for each night of a Qualifying Stay may vary. Promotion may not be used in conjunction with any other package, promotion, group or convention rate, or any other discounted rate. Promotion is not valid on existing reservations and is subject to availability.
