A Google search of Bikini Atoll yielded seven pages of results.
Surprisingly few of the posts appeared to be from visitors to Bikini Atoll.

Travel:  You're route may vary but you'll arrive at Bikini Atoll on
Wednesday.  The uninhabited atoll landing strip is rock and grass.  You
travel by boat to habitation.

Diving:  Diving is world class.  Previous posts indicated that Bikini Atoll
is one of X best dive destinations.  The December 2004 Scuba Diving
magazine, page 20 and page 98, include Bikini Atoll and the USS Apogon as a
"must dive in this lifetime."

Accommodations: Basic.  You'll get an air-conditioned room with single bed
and chair or, if you're in a double, two single beds and chair.  There is
plenty of hot water for showering.  Adjoining rooms have a common deck with
chairs/couch.  There are only two buildings for guests.  The four single
rooms are in one building while the four double rooms are in the other.  Two
single rooms face the ocean and the other two don't face the ocean.  All
four double occupancy rooms face the ocean.  The maximum number of guests on
Bikini Atoll is 12.  (That large a group is generally discouraged unless
sleeping arrangements can be worked out in advance.)

The food is excellent.  However, nothing is fresh.  The food we ate in
November was off loaded from a supply ship in February.  (This includes
eggs.)  The only dairy products, if you want to call them dairy products,
are soft-serve ice cream and powdered milk.  Water is pure.  You will not
have a problem adjusting to strange microorganisms in the water because
there are none.  (A real benefit for those that tend to loosen up while
traveling.)

There is no TV, radio, telephones, etc.  Emergency information from the
outside can be faxed in at $10 per minute.  Yes, there is radio
communications in an emergency.  There is an entertainment room with video
for watching DVD's, etc.

Scuba Diving magazine has pricing information, company names, and phone
numbers.  While they rave about the Apogon as a world-class dive they fail
to mention that all the dives are world class.

Must Have:  You'll need Dan or similar dive insurance and a "C" card (any
card will do),   If you don't have insurance, you need a credit card or
cards to obligate $40,000US for emergency evacuation services.
