The MIL light is never an emergency as long as everything is working okay.
As Woody points out, it could indicate a failure that causes the mixture to
be excessively rich which can damage the catalytic converter. However, if
you drive gently you are safe from that.

Go ahead to the family holiday, but to be safe keep it down to about 80
km/hr or 50 mph on level ground (or equivalent throttle on upgrades) until
you can determine the fuel economy. If it is fairly normal the speed
restrictions are lifted. Short bursts on the accelerator needed for merging
and similar maneuvers are okay in any case.

Do check the tightness of the fuel cap. If it is loose at all, tighten it.
That is the single most common cause of MIL lights, as it shows up as an
"evaporative control system leak."
