Probably better off teaching your kids to enjoy themselves in ways other than focusing on brand, hype, and expense. It's not like Disneyworld is an objectively more enjoyable way to spend anyone's time other than the hype associated with the brand. Do something where you're not travelling a day each way and then waiting in line 1 hour in order to enjoy a mid ride for 3 minutes and then wait in line 1 hour to pay $100 for shytty food.
They'll probably get more moment to moment enjoyment out of the county fair if you hype it the right way.
