Activities in City for my Family?

I need help!

My family is coming into town to visit and I’m super pumped, but I’m stumped on where to take them. It’s going to be a little too hot to do anything outside, and they are of varying age ranges to find a good activity to please everybody (1 yr, 15 yr, 22 yr, 50 yr). I recommended various museums but they aren’t the biggest fans. Any advice would be super appreciated!
