A recent survey ranks whales' bellies ahead of safety-deposit boxes and mattresses as the preferred place to store valuables. Experience one of nature's most priceless resources with today's Groupon: for $20, you get one admission to the three-hour Big Trip whale-and-dolphin-watching excursion from Cape May Whale Watcher (up to a $40 value). Big Trip tours depart daily at 1 p.m. and admission for children 6 and younger is free with each paid adult.

Garnering a smorgasbord of press and awards including recognition from the New York Times, Cape May Whale Watcher guides seafarers on newsworthy expeditions of the Atlantic’s Delaware Bay, boldly guaranteeing every passenger aboard glimpses of a marine mammal. Wading into the bay’s fish-thronged island estuary, the three-hour Big Trip pledges possible sightings of bottle-nosed dolphins, sea turtles, or Poseidon’s weekly trident-throwing practice. Wayfarers then turn their sights to whale watching, veering offshore to tail the bay’s gams of humpback, fin, and minke whales. Set out to sea on the 110-foot Cape May Whale Watcher, a vessel specially designed for crowd-pleasing marine safaris. Cetacean excursions are captained by the ocean-savvy Jeff Stewart, who has narrated voyages in both English and Porpoise for more than 30 years.

While aboard, seafarers satisfy the call for landlubbing creature comforts with amenities including a fully stocked snack bar serving draft beer and wine. The boat has heat and air conditioning for maximally comfortable dolphin viewing and debates on whether or not whales are made of cheese.
