Talk to a coworker and see if you can have them cover your shifts. Let managers know that you're doing it and to let others know that might want the shifts. If they ask why you need the day(s) off tell them you're dealing with a family concern. If they press let them know you appreciate their interest, but it's private. If you can't get someone to cover for you talk to the places you're touring, if they really want you they'll work with you.
