a couple of days for a email-reply to find its way to my inbox.
This could be both good or bad.
They may simply have one person dealing with emails and the school is very busy.
Or the place is a mess and people are answering emails whenever.
School is close enough for you to visit.
Don’t show up unannounced.
It may seem like the right thing to do as they won’t have time to organize a dog and pony show for your benefit but it also means that the people you need to talk to may not be there or otherwise engaged.
I always liked advance notice so I could book enough time out of my day.
