We spent almost two weeks in this resort and I did not miss even one dive. This island is one of best place for dive holidays. May be rooms are not very new but it was not important for us there. Diving is excellent there. All dive sites are not far from island (from 10 to 25 minuts) and we had 3 - 4 dives each day. There is very reach underwater life even without hammerheads.
Restaurant has good selection between asian and european food. Resort has enough big pool and friendly staff.
Dive shop has very good management and diving was organized very punctual. There are no Nitrox but we had very often dives with deep about 40 meters.
But if you are going to spend you holidays in Layang Layang then it's necessary to remember that this resort is good for divers but it's not interesting for non-divers. There even no any entrance to water except pool. Snoorkling is also possible from boat only. Big part of island is closed for walking.More
