Going back to Sweden! BNE - ARN

Check a few months back for a flight and eded up getting one for 1600 return.
So I thought I would put my feelers out as I have a bit more notice this time.

Looking to Fly in Jan/Feb to Sweden.
Would be keen to stop somewhere for a day or so .. no real rush to head back (plus the flight is pretty tough)

Any suggestions?:)

Thanks
