| Why you should go: Belize’s biggest white-beach island, Ambergris Caye is a gateway to some of the most exciting snorkel and dive sites in the world. Just offshore is the UNESCO-protected Belize Barrier Reef—home to the Great Blue Hole, among Jacques Cousteau's favorite dive sites. What’s the big deal? For just $125 per night, two people can spend three nights (or more) in a one-bedroom pool-view villa at Sapphire Beach Resort Belize, a secluded hideaway steps from the Caribbean. You'll also receive daily breakfast. Upgraded rooms with sea views are also on sale. Travelzoo loves: This offer is valid for stays between now through October—a long travel window that includes opportunities to snorkel the popular Hol Chan Marine Reserve and Shark Ray Alley when they’re less crowded than usual. |
