Arguably Club Carlson has been the most rewarding program for in-hotel spend since they launched in 2011.

That’s even after they devalued points transfers to airline miles (and not for the first time), devalued the program across the board, and eliminated the second night free on award stays benefit for co-brand Visa cardholders.

The problem of course is: do Club Carlson’s hotels, like Radisson and Park Inn, work for you? There are some surprisingly nice Radissons, like the one in Downtown Austin (whose bar is the single best place in town from which to watch millions of bats fly out from underneath the Congress bridge) and of course the Radisson Blu brand is fairly upscale. They’re better in Europe than in the US but not actually luxury.

Still, if you can make Radisson and cousins work for you, they’ve got a really valuable program and they’ve launched a new promotion.

Registration is required, and you can earn up to 100,000 bonus points for stays through March 31, 2017.

You have to pick your bonus, and you cannot change once you’d decided. You’ll need to select one before your first eligible stay in order to maximize the offer.

Here’s the choice

• Stay 1 night, earn 5,000 bonus Gold Points
  
• Stay 2 nights, earn 10,000 bonus Gold Points
  
• Stay 4 nights, earn 20,000 bonus Gold Points
  
• Stay 8 nights, earn 50,000 bonus Gold Points
  
• Stay 20 or more nights, earn 100,000 bonus Gold Points

The most points per night is 50,000 points after 8 nights. But you’re going to want to register for the bonus you will certainly hit.

Meanwhile here are the secret rules that Club Carlson hotels know.

Terms and conditions:

Members only need to register once, but registration must be received before checkout of the first Eligible Stay to qualify. Member’s Offer selection at the time of registration applies to all Eligible Stays completed during the Promotion Period and cannot be changed.

Both the check-in and checkout dates of the Eligible Stay must take place within the Promotion Period. Bonus Gold Points will be credited to the member’s account when the standard Gold Points are credited for the Eligible Stay after the required number of Eligible Nights has been completed.
