I just got the reply from Gold Crown Club. They only transfer points from stays at the hotels, not if there is points acrued on the account. Yet. I do not know if that will ever change...
Too bad - that means that my route AMEX to EB pts does not work
I also read that Best Western is a hotel partner of Scandinavian Airlines since February 1st 2005. And that I get 300 EB pts for every night at BW.
