I'll be on holiday in the Czech Rep. (Czarna Hora-Janskie Laznie) for a week in Jan.
you'll love Czech Rep., Janskie Laznie is a spa town, go have some treatments, they are brilliant and expect 5 start treatment for budget prices, spent some time in Karlovy Vary this year which is one of the most famous spa towns in Czech and loved it..
Not sure what snow you'll get for snow boarding though, I would say late Jan early Feb is best time for skiiing over there.
