Parking is plentiful and close to the entrances. Entrances can be found on both sides of the building - you come into a hallway, not directly into the museum but, follow the signs and you'll be okay!
Bathrooms are in that same hallway - you'll find the code inside the museum for when you need to go. One has a changing station and step stool.
If the Community Room is open, you are welcome to bring food in and eat in there, as long as you tidy up after yourself when you're all done! There are several wonderful restaurants in the area if you'd rather leave and come back. Your admission fee is good all day long!
If you forgot diapers, a change of clothes, wipes, bandaids, ice packs, or snacks at home, the museum usually has some spare supplies on hand. Just ask for what you need, you never know what we might have around!
