shedd aquarium: I'm planning a trip for 2 adults and 2 children to Chicago. We will be arriving at 1pm on a Thursday and will have to go check in at our hotel and leaving on Sat at 4. I'm trying to plan our itinerary based on how much time we have. I've thought about purchasing the City Pass or Go Card, but am not sure if it will be worth my money given the amount of time. We would like to visit Navy Pier, Skydeck, Shedd Aquarium, and possibly Field Museum and Museum of Science & Industry. They all have a little something we'd like to see. I'm unsure of how much time we would need to spend at each attraction. The positive thing with purchasing a Go Card or City Pass is VIP entry, no waiting in most lines. Could anyone make any suggestions on the best way to go and the best savings ? Thank You!|||Check out the Fodor's and/or Frommer's guides for Chicago, either on-line or the books [they probably have them at your library]. To do all of those things would really have you constantly on the go, and with two kids [depending on ages] that may not be practical. Your best bet is to choose two or three of those things. Incidentally, if you want a great view of Chicago, you can do it for free, or for the cost of sodas, by going to the Hancock Building and going to the restaurant on the floor below the observation deck. Same views, no admission. If you're there at the right time of day [we went mid-afternoon - lunch crowd was gone], they may even let you just look without buying a drink. Have fun
