Yes, it's far to walk to Navy Pier. Take the water taxi - besides saving you the walk, it's fun, and convenient to Union Station. You may have to wait a while for the taxi, but in the morning you'll be waiting in the shade.
I usually buy my return ticket when I arrive, rather than wait until I'm ready to leave; that way if there's a time crunch, I don't have to worry about missing the train because of time standing in line to buy the return ticket. Definitely buy the return ticket in the station, rather than on the train - it costs less. (Surcharge for buying on the train when the station you are traveling from has a ticket office.)
In addition to the dog and pizza, you gotta try an Italian Beef Sandwich. They are unique to Chicago. Order it "wet". Extra's might include cheese (cheezy beef), with sausage (combo) or with hot giardinara or sweet green peppers. You can find these at any hot dog stand and most pizza places in Chicago and the suburbs.
Thank you kknowlton for the info on the water taxi and train tickets, we don't arrive to the KOA until late Sat. night and plan on going into Chicago Sun. morning. Not ever being to Chicago before is a little intimidating, so all the info I can get is very helpful.
Also, thanks Haftacamp for the info on the Italian beef sandwich. If I order it "wet" whats on it???
We are staying at the Chicago NW KOA and are also going to Six Flags for a day. Is one day enough? Is anything else worth seeing around the KOA or Six Flags area?
How long are you staying? Six Flags is worth many days if you're a kid or a wild ride afficionado; otherwise, not (for me, for example). I believe they do have a policy that you can get in two days in a row for the price of one - ask about it.
Make sure when you get your train ticket to ask for the weekend rate, if that's all you'll be using it. It's less $ on weekends than on weekdays.
Near the KOA is a train museum (outdoor, for the most part) which we have enjoyed. If you're into horses, and have Wed. morning free, check into a really unusual treasure we have here in Lake County (not far from Six Flags), the Tempel Lipizzans. (http://www.tempelfarms.com/) They do shows twice a week, and - again, if you're into horses - they're worth the price. Nothing glitzy or circus-like; the trainers and horses (or their grandparents, anyway) came from the Spanish Riding School in Vienna.

Thanks
LOL...Italian Beef sandwiches are traditionally served with beef juice soaked on the bread. The more the better.....unlike a east coast "hoagie" which is served on dry bread dry.
