FIBR and Coco View share the same Lagoon for their shore diving. The wreck in the lagoon is a must-do dive, especially at night. The boat is encrusted with soft corals and sponges and all sorts of critters.
If you are contemplating which place to stay I would have to recommend Coco. I haven't stayed there, but have stayed at FIBR and must say it is the worst place I've visited in the last 4 years----and I do about 6 trips a year to various places. The food sucked, my room was old and mildewy smelling with worn out beds.
The dive boat broke down two days in a row and had to be towed in. Our second tank dive ended up with us being dropped in the lagoon. No opologies or any compensation for this loss. That was two years ago and from what I read it hasn't gotten better.
The "lockers" are open air with no doors and no locks, used on a first-come first-serve basis---each day. Things have been known to disappear frequently.
I always hear good things about Coco. I do have to say that I did enjoy the reefs there. Lots of soft corals and critters. Deep dives, shallow dives, wall dives. The shark dive at Wakaluka (spelling) is not to be missed even with the extra charge.
