Go to Meow Wolf in Houston!!! It’s immersive art- so think art museum that you can touch the walls and interact with the artwork. Their experience in Houston is called Radio Tave. Give yourself a good amount of time to explore an wear comfortable clothing/shoes. Meow Wolf does attempt to make their art installations accessible for all sizes, ages, and abilities- so if you visit while on crutches, on a walker, or in a wheelchair, both you and your dad should still have an enjoyable time! Hope it all goes well!
