I hate to admit it, but I was disappointed with the place. I mean, it was cool to see the house and play with a red rider bb gun and leg lamp, but I think the $10 per person admission price is too steep for what you get.
There was a long line (being Christmas season and all) and because of that, there were no guided tours. Instead, you were sort of funnled/rushed through the house and encouraged to "read the brochure if you want information about the house" I'm sure the experience is better when guided tours are available, so my advice is to try it out then.
The museum portion was small, and most of the items on display were not originals or were obscure pieces. I expected to see something like the original leg lamp or a bunny suit. Instead it was photocopies of original scripts and letters and obscure costume pieces. Actors with bit parts in the movie (the guy who delivered the leg lamp and the elf from the department store) were at the museum to give brief bits of info and sign purchased merchandise.
Parking in the area, especially when it is crowded, is sort of a nightmare. Narrow streets are fully parked up so we gave in and paid the neighbor $15 to park.
It isn't that I didn't have a good time, I just feel that the ticket price should be more like $5 and they should work on improving the quality of the museum's exhibits.
