When it’s cold in northern North America, it’s high season in the warm reaches of the south — especially in the Caribbean — as snowbirds flock to sunnier shores.

High season ushers in high prices, but bargain seekers can claim a stretch of sand by considering the value of all-inclusive resorts that bundle meals and activities into the rates. For example, Iberostar Waves Costa Dorada in the Dominican Republic offers a beach, pools and five restaurants (doubles from $170 a night for two). Liberty Travel, an agency based in Montvale, N.J., and known for its expertise in the Caribbean, steers clients to the Grand Palladium Jamaica Resort & Spa for its four beaches and multiple dining options (from $285 for a double).

But for those seeking a D.I.Y. getaway, the following destinations allow travelers to stretch their budgets this winter.
