The overall reputation of Shedd Aquarium is positive based on the collection of reviews provided. Customers are generally impressed by the variety of exhibits and the opportunity to engage with marine life, such as the ability to touch starfish and view animal spotlight shows. The aquatic displays, particularly the shark tanks, dolphin area, and penguin observation section, are highlighted as some of the best features of the aquarium. Guests appreciate the educational value and the care exhibited by the keepers toward the animals. While the aquarium is currently undergoing construction, it seems to have a minimal impact on the visitors' experiences, as many exhibits remain open and enjoyable. It's noted that the facility is larger than some guests initially perceive and that multiple visits or several hours are required to fully explore the offerings. Despite the enthusiasm, some visitors mention logistical drawbacks regarding crowds, wait times, and unclear viewing conditions in some exhibits. Parking challenges also arise as a minor point of contention.
