[For hotel guests] Glassbottom Boat Cruise
A glass-bottom boat is a boat equipped with glass windows in the hull. You can get a close-up view of the beautiful underwater world—including colorful tropical fish and coral reefs—without even getting in the water. Whether you’re someone who “isn’t quite comfortable with snorkeling,” a young child, a senior citizen, or a person with a disability, anyone can easily enjoy a stroll through the ocean. One of the attractions is that you can participate without worrying about the weather, as you can observe the coral and colorful fish underwater not only on sunny days but also on cloudy or rainy days. There are six departures per day. The trip takes about 30 minutes, making it easy to join. ◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇ Guests who meet any of the following criteria will receive a complimentary glass-bottom boat tour once during their stay as a special benefit. ・Marriott Bonvoy Platinum Elite members or higher ・Guests with a reservation in the South Tower ・Guests with a reservation for an “Ocean Suite” or “Ocean Maisonette” in the Main Tower Advance reservations are required.
