I received a response from Radisson about my eligability to earn 50,000 by staying in a Radisson Blu or Radisson. It appears I am eligible since I registered for the promotion by 10 AM CST this morning. Below is there response.
It looks like the 50,000 promotion is still available. Good news for all of you who got a full night sleep and in on the deal with me. Looks like we can proceed with making reservations to participate in the promotion. Any ideas which hotels are participating?
