The price is right for this universal dream of escape to paradise: around fifty bucks. Catamarans take off right from the beach at toddy time, 5 o'clock.
The hour-and-a-half cruises usually include all the beverages you can drink, although land lubbers want to be careful with that proposition, since being bombed and seasick at the same time is not fun. But waters are normally flat near shore Waikiki, so not to worry. The resort strip at night seen from the water is an awesome sight.
