Can my mother do the first nursery school visits instead of me?

We're planning for nursery in June 2027 and I'd like to see four or five schools around Domalguda and Himayatnagar before the forms open. Every school I've called says visiting hours are weekday mornings, 10 to 1. Those are my theatre and clinic hours, and I can't take five mornings off for first impressions. My mother lives close by and would happily go. Do schools take a grandparent seriously at a first visit, or does it come across as parents who aren't bothered? I'd go myself for anything that looks like a shortlist.
