As others have pointed out, resorts have no control over how their guests treat each other. Beyond that, it sounds like the OP just had different expectations than what LCBR could provide. Expecting 5 star accommodations, food, and service at a 40 room dive resort on a very small island for $2k or less is unrealistic. At LCBR you get very good service (for a dive resort), very good food (for an all inclusive diven resort), and the best dive operation I have ever been with. If the OP found the diving to be boring, I suspect that they were used to tightly guided dives with a DM pointing out what to look for. If you are not used to the freedom of not diving with a group and don't know how to look for things, I could see where one might be a bit lost and not feel like they had seen much.
in any case, thanks to the OP for an honest opinion of their experience...I have had a very different experience on my trips to LCBR, and will be going back in September (for about $1350 pp)...but I guess not everybody will love every place.
