...but I think the Unofficial Guide for
Disneyland has a section on Universal. Fodor's also has a good guide for the area that includes Universal.
As for characters...they're rare, but they do pop up here and there. I remember seeing Woody Woodpecker. And I think some of the Rugrats kids drop by. But they aren't nearly as plentiful, or as familiar and beloved, as the Disney ones.
Generally, I think, Universal is not geared as much to kids; most rides are linked to thrills or to the movies, and wouldn't appeal to little ones. (A notable exception is "ET" -- which bears a more-than-passing resemblance to "Peter Pan's Flight" at DL, but is more intense and realistic, I think.)
