shedd aquarium: I was planning on visiting Chicago IL. for a day. As I was looking up train tickets I noticed just about all of them would give me 6hr.s to see all the attractions I am interested in. Do you think this would be enough time to see things like the Navy Pier, Shedd Aquarium, Millennium park and ect.?|||If you stay in the downtown Loop area, you'll be close to the pier, Millennium Park, Sears Tower, the Art Institute, Buckingham Fountain and the Museum campus (Shedd, Field museum and Adler Planetarium). But while six hours may seem like a lot of time, it can go by quickly if you're sightseeing. For instance, the three places you named (Pier, Shedd and Millennium Park) aren't right next to each other; you have to give yourself time to get from one to the other. You could conceivably walk from one to the other (if the weather is nice), but that's time you have to take into account in your six hours. If I had to pick, I'd spend a couple of hours at the Shedd, a couple of hours at the Art Institute and an hour at Millennium Park. Navy Pier is overrated. There's really nothing to do there but buy junk. Yeah, there are a couple of restaurants there, but they are overpriced in my opinion. Skip it.|||Sure, six hours is good if you focus on the area between Navy Pier on the north and Field Museum on the south. Navy Pier has an outdoor amusement park with a Ferris Wheel, you can get some great pictures of the skyline of the city from here. If you don't have time for a sit-down lunch, just grab a bite from an outside vendor. Shedd Aquarium just re-opened their Oceanarium. You have to go to Secluded Bay and watch the baby belugas; and the otter habitat is awesome too. You might like Millenium Park too. Stand next to the giant "Bean" sculpture and see yourself reflected against skyline- makes for great pictures. You can choose a more upscale lunch in one of the outdoor cafes (they also have indoor seating if you prefer). On Michigan Ave., The Art Institute just opened its Modern Art Wing. Admission is $18 for the main galleries. Enjoy and promise to come back to Chicago when you have more time!|||Definitely! Navy pier and Millennium park are really just things you will want to breeze around take a few pics and move on. Shedd Aquarium and The Art Insititute I would allow 2 hours for. As long as you might be willing to take a cab once or twice you can for sure do it. Have fun!
