You can park your car for free in parking garage Stationspark, Maria Theresialaan 12. This is right behind the NS railway station. Within 5 minutes walk you are at Hotel Roermond Next Door.
When entering the parking garage, you will receive a ticket that you can have stamped at the hotel reception when you check out. This way you leave the parking garage free of charge.
Coming by bike? Then park it in the bicycle shed at Hotel Roermond, Stationsplein 9 (across the street). And charge your bicycle if necessary.
