You should schedule 2 or 3 days in Majuro. Raycrew is the only dive operator at the moment. Ask them to take you to the Aquarium, both incomeing and outgoing tide, Garden of Eden, Marker #9, Ennemanit Island, and try to get over to Arno Atoll, weather permitting. Kwajalein has more wrecks than Chuuk, everything from airplanes to the German heavy cruiser Prinz Eugen. Finding an operator can be difficult if you are not staying on the army base. Hideo Milne is the only guy I know operating out of Ebeye Island. Good luck and enjoy your trip.
