The Chicago skyline is truly something to behold, but to see the whole thing, you'd better be able to walk on water or have a boat. Choose option B with today's deal from Vantage Yacht Club: $99 for two hours of electric boat rental on the river and harbor for up to ten people (regularly $300). Head down to the Kingsbury Marina, where this private yacht company is opening its fleet of electric boats to the public -- stately vessels that require no gas to run. Vantage's staff is on-hand to help you in and out of the boat, and from there, the water is yours to explore. You can BYO party favors or opt to reserve a boat fully stocked with booze, drinks, and locally catered food for an additional fee. And with savings like these, your maritime voyage through Chicago can be as cheap (and easy) as a stroll along the Riverwalk.
