This place is a MUST if you have friends or family visiting from out of town, or if you are a giant pop culture nerd like myself.
We went on a Saturday, and it was busy, but not overwhelmingly so. I love that the house itself is interactive. Do you want to crawl under the sink and hide, because you're worried "daddy's gonna kill Ralphie"? Go for it. Sit at the table and read the newspaper? Do that, too.
There are tons and tons of photo opportunities throughout the house. I especially love that there are props (hats, bb guns, even the Pink Nightmare costume) throughout, and you are encouraged to use them.
