Phil. I apologise. You did not say rebrand. Despite your flame, I do indeed agree with much of what you said.
However I repeat that whoever comes on holiday to Belize whether eco tourists or "conventional-type' they will still be put off by high airfares relative to surrounding countries as they are right now.
The BTB is the government department charged with overseeeing and promoting tourism in Belize, and the BTIA is the tourist industry's trade body. Please correct me if I am wrong.
Many people think that high airfares are the single biggest factor in incresing tourism. I happen to agree and my experience in my own resort here bears out what others have said.
Of course all the things (crime,litter training etc) you mention are important, here we agree again.
My point is that the BTB and BTIA are those we must look to. I do not accept there is "not much" to be done about airfares. That is the counsel of despair.
