NEW YORK (CNN/Money) - Spring officially started on March 20, although you'd hardly know it if you live in the Midwest, where it recently snowed as temperatures struggled to get above freezing.

Even if you have been blessed with genuinely spring-like weather, you might want to consider packing your bags for some place even sunnier. As of April, resorts in the Caribbean, Mexico and other balmy destinations started reducing their rates to off-season levels.

"Some of these resorts drop their rates by half," said Martha Gaughen, a travel agent with Sterling Travel in Atlanta. Resorts don't just cut their prices, they also reduce their minimum stays and offer all kinds of perks. At Hotel St. Barth Isle de France in St. Barts, a beachfront room is $750 a night during peak tourist season. But in the off-season the hotel offers a one-week romance package in the same room for about $500 a night, and that price includes daily breakfast, a dinner for two, cocktails every night and a car rental.

Even Hawaii is on sale. From April 14 to June 7, for example, United Vacations is offering roundtrip airfare, five night's accommodations and a rental car for $864 per person from New York and $574 from San Francisco. During Hawaii's busy season you would pay that much for airfare alone.

The fact that fewer people visit America's paradise after March has little to do with Hawaii's weather. "Right now the weather is no different than it was in January or February," said Gaughen. "It's beautiful all the way through July." Rather, spring break has come and gone, summer is off in the distance and most people no longer feel the need to escape to warmer places.

While this seasonal slowdown happens every year, travel agents are seeing prices drop sooner and more drastically than in years past. "There are a lot of discounts to get more people traveling and fill seats and hotels," said Renee Coon, a travel agent with North Coast Travel in Erie, Pennsylvania. She recently booked some of her clients on a seven-day trip to Cancun for $625 per person, including airfare, meals and accommodations at a four-star resort.

Since off-season bargains are common at tourist destinations, you should not have a problem finding deals at your favorite resorts. If you put together your vacation a la carte, however, you may find that plane tickets to some of these places have not come down as drastically as the room rates. "Airfare the last couple of years has stayed as high for low season as it was for high season," said Gaughen.

A better bet might be to look for air and land packages offered by tour operators like Apple Vacations or Funjet Vacations as well as the airlines' themselves. When a resort needs to fill rooms or an airline needs to fill seats they often go directly to the tour operators, who in turn bundle and sell packages. These packages are typically priced per person and include airfare, transfers, accommodations and even meals. Many tour operators work exclusively through travel agents. (They pay the agents a commission, so you pay nothing to the agent.) A few sell directly to retail customers.

While warm-weather retreats are where you'll see the most drastic price cuts in the spring, travel agents say they're also seeing discounted airfare and hotels for Las Vegas, New York, New Orleans and all of the major ski resorts. "I've seen $399 air and hotel packages from the Midwest to Las Vegas," said Coon.
