Award-winning Half Moon Cay, Holland America Line’s private Bahamian island, celebrated its 15th anniversary this Caribbean cruise season, and to commemorate the milestone the cruise line has enhanced island offerings and features.

Guests to the island will notice five new, colorful, two-story Beach Villas available for rent during each call. The luxury hideaways boast exclusive hot tubs on the second floor and provide private accommodations for guests while they relax and experience the island’s highlights. Other beach cabanas were refreshed, and the Grand Cabana received new décor and a slide from the cabana deck straight into the ocean.

“For 15 years, Half Moon Cay has continuously been recognized as the most popular private island in the Caribbean, and to celebrate this milestone we have added several new features,” said Richard Meadows, executive vice president, marketing, sales and guest programs. “Our guests already rate Half Moon Cay as their favorite Caribbean port call, and these new enhancements will make the island even more enjoyable.”

A new glass-bottom boat that carries 290 guests also was introduced for tours and features underwater viewing of the island’s colorful reefs and sea life. The horseback riding tour is one of the island’s most popular, and six horses were recently added to the herd so more can enjoy the ride.

The enrichment of the island’s features extended to the Bahamian Church, which has been repainted and outfitted with new pews and interior artwork. The island’s private chapel is nestled in a garden overlooking the sea and provides the perfect setting for cruise guests to enjoy a unique, romantic wedding ceremony or vow renewal.
