I think you were probably wise to not request that meeting, but if they are inviting you, why not? Wear something nice and thank them profusely for their time.
@Aidoe Yes, schools give out fee waivers based on LSAT score (but also for other reasons, too). You still need to pay the LSAC CAS fee, which is around $30 per school, although that can be waived based on financial criteria.
