Just a heads up Radisson rewards are having massive IT problems at the moment, with extra night and extra stays appearing in the account for some and vanished for others.
My account jumped +10 nights for no apparent reason and my year end status nights deduction end 7/2024 hasn't happened.
There are other examples in the RR thread.

If you have an RR account you want to link to this offer I would expect difficulties!
But not if you create a brand new account.
