$11 per adult gets you into the Mark Twain home, Huckberry Fin house (it's tiny), museum and several other properties. From that standpoint, it's a great value. I was expecting to see a bit more, but I by no means feel ripped off. If you're a fan of Mark Twain or a history buff (like me) you'll really get a kick out of all of it. If you're not into this stuff (like my wife), it will be slightly boring but tolerable. Video and flash photography are allowed for all but the original Norman Rockwell paintings in the museum. Nice, clean bathrooms are always within quick walking distance.
