Thanks for the update but with their poorly thought out move to make you choose one or the other program they lost me as a customer. I suppose that if I return to Tallinn I might stay again at the Scandic - same for Olso Train station, and outside of Stockholm the choice is pretty limited to Scandics - but aside from that I can't see ever choosing Scandics. I for one would have joined if I could have been allowed to just transfer some points and kept most of my points with Hilton. But its their business to run as they see fit.
I'm glad they were part of Hilton for a while, especially back when they were all category one hotels but its time to move on!!
