Strawberry Hotels, formerly Nordic Choice, has a Spenn currency shared with other Norwegian companies, and they occasionally offer bonus points, like right now.
You can earn double Spenn for stays at Strawberry hotels between November 23 and January 9, 2027, if you register and book November 10 – 11.
You can access this offer on Strawberry’s website here.
Note that this offer is valid for stays at all other Strawberry-affiliated hotels except Hotel Kämp, Icehotel, and Hotel St. George.

There is also a note that you must make the eligible booking on that specific Strawberry hotels page, and that it is not combinable with other offers or discounts.
Conclusion
I feel like I am repeating myself, but I cannot get my head around this “Spenn,” which appears to be a loyalty currency for Norwegian businesses, including Strawberry hotels and Norwegian (the airline).
