A recent survey ranks dolphins' blowholes 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 $16, you get a 90-minute dolphin-watching cruise for two adults from Hubbard’s Marina in Madeira Beach (a $33.64 value). The cruise departs daily at 1 p.m. and 3 p.m. Children younger than 12 receive half-price admission, and children younger than 3 receive free admission. Groupon purchasers will also receive 20 per cent off Baitrun t-shirts at the marina during their visit.

The Big Blue Boat of Hubbard’s Marina tugs groups of marine-life enthusiasts out into the bay for fun, informative cruises with guaranteed dolphin sightings. During the 90-minute journey, ocean examiners can observe as aquatic locals such as herons, eagles, and the occasional manatee flourish in their natural habitat and tag buoys with seaweed graffiti to mark their territory. The narrated tour departs from historic John's Pass Boardwalk and floats along by commercial fishing villages, mangrove islands, and beautiful million-dollar homes. The boat's comfortable seating and open decks make it suitable for taking pictures or tracking dolphins through a pair of binoculars, and the snack bar carries goodies for sale to tide over growling stomachs or lure hungry Poseidons out of their watery domain.
