Not all Chicago-by-sea tours are the same. Maybe we don't want to gently glide down the Chicago River, casually waving at passerby on La Salle. Maybe we wanna tear things up on a speedboat, huh? Seadog Cruises offer sightseers three unique Chicago adventures accompanied by narration and music, including one called a water rollercoaster that we're just dying to try. The best part? Your furry friends can get in on the action, too! Dogs are allowed (for free!) on all Seadog Cruises! We strongly recommend booking reservations early$mdash;excursions run only from Memorial to Labor Day. Seadog Cruises, 888-636-7737.
