M.C.
I have not been to Navy Pier for Santa. We personally are not big fans of Navy Pier as it tends to be way over priced, even for Chicago. What I would recommend is going to the Walnut Room at the Macy's on State Street. That's a classic and it's absolutely beautiful there. You will LOVE it and your girls will be amazed at the splendor. And I'm sure being that it's a Macy's, Santa will be there too. FYI - the Walnut Room is a restaurant but decorated extravagantly. It's been a family tradition for us to go there for Christmas, as many other families do too. It really is a sight and just a lovely experience. The Kringle (sp?) market is across the street also. That's a lot of fun to go see as well.
