Forget the flowers, the chocolates, or that mango-colored thong. Before Thursday rolls around, get you and your girl a trip someplace warm. So she can lounge in the sun, go kayaking or snorkling, or take a surf lesson with some guy considerably hotter than her husband. In return, you get to do this:

And she gets to do this:

And everyone is happy. Here is a list of three great places to start:

Turneffe Flats, Belize

For one of the best combinations of excellent flats-fishing and great food, accommodations, and alternative activities, head to Turneffe Flats off the northern coast of Belize. This place offers probably the best shot at a Grand Slam (permit, tarpon, bonefish) in the Caribbean, and with scuba, snorkling, kayaking and birdwatching, there’s plenty for the no-angler to do as well. www.tflats.com

Campeche, Mexico, on the Yucatan Peninsula

Take the relatively short flight to Merida or directly into Campeche and see why this has become one of the hottest destinations in the Yucatan. Affordable hotels and restaurants, several Mayan ruins to choose from, plenty of shopping, a much more mellow gringo scene that Cancun, and best of all, miles and miles of baby tarpon fishing just north of the city. www.campechetarponbay.com

Plecentia, Belize

Not only does this tiny peninsula in southern Belize offer some of the finest flats fishing on earth—on both the ocean side and the large lagoon on the inland side—but you are also close to the vast array of other activities that this part of Belize has to offer, from birdwatching and jungle tours to visiting the nearby jaguar sanctuary. And the beaches found near Placentia are nicer than in other parts of the mainland. www.yellowdogflyfishing.com
