no problem. you can store your luggage, there is a SNCF luggage counter where you can store your luggage. don't ask me what it costs, but for sure its easy to find, just between arrival and the great departure hall.
if you have time at Strasbourg, don't miss the christmas markets next to the cathedral ^ ^
