Advantage Boat Club's skilled chauffeurs launch pleasure-craft from the scenic shores of Lake Minnetonka, genially hosting cruises with complete amenities. Parties of up to six board a fully stocked vessel for a six-hour cruise, enjoying scenic vistas of woodsy shoreline and regal bird parades. BYOB beverages act as icy coolers to keep swimmers from dipping their straws into the water or trying to wring out seaweed into their mouth. The Club's complimentary waterwares cater to guests' wave-top needs, from life jackets for kids and adults to towel service for mopping up splashes and swaddling torsos during spontaneous toga parties. Enjoy brisk breezes and rile up waves while waterskiing (skis provided) or dive and swim off the anchored boat with a selection of water toys.
