We are planning on taking our girl's to the American Girl Place in Chicago in the spring. I am looking for some advice. :-)

When is the best time to go? I hear they are always busy, but is there a slower time to go? Is a cetain day of the week better than others?

Is the theatre worth it? How much do you have to pay for the hair salon? Are the packages the best way to go?

Any tips, ideas, stories, hotel reccommendations....any feedback would be great! Thanks!
