Having a spare hose is a very good idea for when washing the hose as there's no rush to get it dried, but it is also advisable, if possible, to have an extra hose for the inconvenient times when the hose may incur damage, as it saves fumbling at night to find suitable gaffer tape for a temporary repair!
