31 All-Inclusive Vacations That Cost Less Than a Flight Alone

12. San Andrés Island, Colombia

Tucked away in the Caribbean Sea, San Andrés Island is technically part of Colombia, yet feels like a world apart—blending Afro-Caribbean culture, Creole charm, and stunning natural beauty. The island is encircled by coral reefs and ringed with some of the softest, whitest sand you'll ever step on. All-inclusive packages—including round-trip airfare—can often be found for under $700, making it one of the Caribbean’s best-kept secrets for budget-conscious travelers. Resorts typically offer beachside dining with fresh-caught seafood, unlimited tropical cocktails, and complimentary activities like snorkeling, island tours, or kayak rentals. Don’t miss “El Acuario,” a shallow, crystal-clear natural pool perfect for spotting starfish and stingrays. You can even wade between cays at low tide. The island is also a duty-free zone, so shopping for perfumes, electronics, and souvenirs is surprisingly affordable. With fewer international tourists and a laid-back, barefoot vibe, San Andrés offers a tropical escape where your dollars stretch as far as the horizon.
