The Horizon day sail sets off at 9am and returns at 4pm. Breakfast is included and served to you (muffins, breakfast breads, etc) along with mimosa or hibiscus drinks. Lunch is also included--a delicious Italian buffet.
Snorkeling around St. John's in the morning (equipment and lessons provided) or just swimming with a "noodle" is a delight. After lunch, more water time at a private beach area. Open bar and party time (or sleep time) throughout the day. Definitely worth the price!
