Even though water covers most of the earth’s surface, humans spend most of their lives on land and a small portion in the air while they’re sleeping. Float on with this Groupon.

Choose Between Two Options

• $42 for a three-hour dinner cruise aboard the Spirit of Philadelphia, redeemable Sunday–Thursday (up to an $88.31 value)
• $50 for a three-hour dinner cruise aboard the Spirit of Philadelphia, redeemable Friday or Saturday (up to a $99.03 value)<p>

During a three-hour cruise, guests take in views of Philadelphia’s historic skyline from an expansive open-air deck before being escorted to a candlelit table, where they can feast on a dinner buffet equipped with a carving station and enticing desserts. During meals, Spirit’s talented staff serenade guests with renditions of popular songs before a DJ encourages dancing on a newly renovated dance floor by spinning beat-heavy tracks amid LED lights and plasma TVs. Boarding begins at 6:30 p.m. Monday through Thursday, 7 p.m. on Friday and Saturday, and 4:30 p.m. on Sunday.

Though Spirit of Philadelphia sometimes features a discounted price online, this Groupon still offers the best deal available.<p>
