FTM here but I've been told to preregister and get all paperwork out of the way so that you aren't stuck doing that in labor. Also ask about whether baby can room-in with you and what the protocol is for any visitors you may have. Mine is in a few weeks, good luck!
I was looking through the third trimester guides on my app last night and saw the bump has a guide for this! I think it was even labeled what to ask at my hospital tour or something really close. If I have more time at the airport later I'll figure out if I can post it here from the app (probably not. Nothing really works on the app!) But I thought "go look for it" was more helpful than sayi nothing about it.
Here's the link @edavis926 was referring to. Most of these questions will probably be answered during your tour, but always good to ask if they don't cover them.
