Hawaiian Waters Adventure Park frequently offers promotions with up to $10 off the regular admission price. It's a good idea to call the park for information on the latest promotions. 

Since you'll probably want to spend most of the day at the park you may want to bring your own lunch. Coolers, food, alcohol or beverages may not be brought into the park, though there is a picnic area outside that is set aside for eating. Don't worry, a stamped hand allows access in and out. Picnic tables and shade pavilions are on a first come first serve basis. You may also choose to eat inside at one of the Park’s many several snackbars. 

The park advises you not bring valuables if possible. If you must, then you will have to rent one of the parks lockers. They can be rented for $3 a day, plus a $2 refundable deposit. 

Remember, Hawaiian Waters Adventure Park is on Oahu’s leeward side. This means sun, and lots of it. Don’t be fooled by the relative coolness Hawaii’s tradewinds might bring – take your sunscreen and apply it regularly. It makes good sense to wear slippers rather than shoes to the Park. They can easily be purchased for a few dollars or less at a local drugstore. 

For an extra fee roundtrip bus transportation is provided between the Hawaiian Waters Adventure Park and designated Waikiki Hotels. You should call the Park’s reservation office at (808) 674-9283 ext. 107 to get pick-up locations or to make reservations.
