Where can I take my 10 and 13 yo nephews to entertain them?

I am on auntie duty next week and am scratching my head about what to do w them. Seems like we’ve done everything. Done the slime museum, andretti’s, Dave and buster’s, zoo, Johnson space center, aquarium. Don’t know what else to do. They’re active kids, they don’t have the attention span for museums. Aside from driving to Dallas or San Antonio, any ideas w what I can do?
