What do you think of plastic tablecloths vs linen for wedding receptions?

Do people really pay much attention if you have linen or plastic on the tables for tableclothes? We are talking about a $1500 plus expense for linen, which would be pretty,......but is it really expected as long as we have great food, great band playing and free drinks???? I'd rather spend that $1500 and use it to upgrade to a very romantic suite in Cancun then on tables.
