How long? If its more than say two hours the pasta will turn to mush.Your best bet is to severely under cook your pasta, like just a few minutes in boiling water, this way it will take much longer to turn mushy.
I don't think it's a problem. Make sure you have plenty of sauce as the pasta will absorb it as it sits.
