I went on Friday December 8th. I have gone to the crafts fair for just about as long as I can remember. It was about the same as usual, fun to stroll through and there were lots of cute little crafts. It's always worth the price, it's about $8 to get in and free if you buy a park ticket.
The ice show they had was new this year. At first I didn't like it at all, they tried to modernize the Peanuts and they played alot of hip hop/dance music that wasn't terrific. But towards the end it got better as Linus did his true meaning of Christmas speech (to which the audience applauded it was wonderful) and they paid homage to the nativity to scene.
I also got the pleasure of seeing Knotts try to do their first Christmas parade. I don't want to be too cynical since I'm a Disneyland APer I am quite a bit spoiled.. but the parade was awful. The characters were static, the floats were dirty, there was no music besides one little elementary school band that walked by (with their shirts untucked and their music way out of balance) and no sound except for Lucy who said something (I don't remember what she said).
All in all, if you've never been to the crafts fair I suggest going for a stroll, it's nice and usually not crowded. The ice show is your choice, I found it quite enjoyable but very different.
