All-inclusive resorts are notoriously affordable in the Caribbean, but when you throw in a free night, it’s even better.

Secrets Resorts and Dream Resorts in Riviera Maya, Cancun and Puerto Vallarta are offering the third night free when you book with Orbitz. These 4- and 5-star resorts are great if you’re looking for an adults-only resort.  Nightly rates start at $199 at Secret Resorts and $162 at Dreams Resorts.

These resorts are part of a larger all-inclusive sale with Orbitz, with locations in Punta Cana, Jamaica and the Bahamas. As part of this offer with Orbitz, most resorts are offering some type of discount on nightly rates. Palace Resorts will include a resort credit of up to $300 and free dolphin swims.

If you’re not familiar with all-inclusive resorts, they include accommodations, all meals, beverages, entertainment and activities. Select water sports are included in the price, but check with the individual resort.
