Lakes allow for the aquatic fun of the ocean without the pesky undertow, oversalted water, and loads of junk mail jammed into wine bottles. Live the lacustrine life with today's Groupon to Holiday Harbor Marina & Resort in Acworth. Choose between the following options:

• For $65, you get a two-hour jet-ski rental (a $150 value).
• For $75, you get a one-night cabin rental for up to six people (a $175 value).

Holiday Harbor Marina & Resort, which is located approximately 25 minutes north of Atlanta, rests on the shores of scenic Lake Allatoona in a wilderness escape teeming with family-friendly fun. Up to six people can spend a night in one of the resort's seven fully furnished cabins complete with two bedrooms, a lakeside porch, and a kitchen. Roast marshmallows over the communal fire pit, or grill burgers, hot dogs, and wookiee ribs on the group-use grills. Guests can reconnect with the concrete jungle via wireless Internet and satellite TV.

Alternatively, guests can stretch their sea legs for two hours on a rented jet ski. Dash across the lake's serene waterscape aboard the fast-moving vessel while vested in an included life jacket. Back on land, erstwhile seafarers can replenish nutrients stolen by hungry starfish in the resort's on-site restaurant or investigate nearby hiking trails and attractions.

Fuel is not included in the cost of jet-ski rental.
