The post(s) about the prices are fairly accurate; having said that, the trip is well worth the cost. Like a restaurant, if the experience is great, the cost is not material. I was fortunate to have the time and resources to spend two excellent weeks there in late September and early October of this year. All up the trip was on the order of $7,200. Would I do it again? Bet your bippee I would. My wife won't do deco diving, however, so the next trip is to Truk. We've been there several times, and the wreck diving is great. They do a shark dive, but I wouldn't go there just for that. Bikini also does a shark dive, but it largely depends on the weather. The sharks are way across the lagoon, and its more than an hour each way. We went the first week I was there, and did not on the second week. It also depends on what the majority wants to do with that particular day. If you're into green rocks and fish, the cost of Bikini is hard to justify. If you want to visit the most interesting wreck dives in this world, then Bikini is a must-see stop on the tour. The only frustration is the Marshall Air link to Bikini from Majuro. They have two airplanes, and connections depend on at least one of them being "up" when you need it.
