Maternity tour 🏩

I'm a FTM & currently 19wks.  The hospital that I plan on delivering at has days they do maternity tours of the hospital.  They have about 4-5 tours a month that you can register for at varies times.  I planned on delivering my baby alone, I don't want anyone to be with me while I'm in labor.  But I wanted to know, is it too early to have a maternity tour now or should I wait until I'm closer to my due date.  I want to get the small things over with early before my bump gets too big but I know some things should be left until the last minute.
