Good or Bad - I bought some land in Puerto Vallarta in 1981-I had only heard of the place from the "Love Boat" series until I visited the place which I found to be relatively idyllic-look at what has happened the residents of Jallisco have benefited hugely from the cruise boats and from tourism in general.
If Belize invests in infrastructure,and the gov't allows everyone to make a few shillings (rather than the favoured few)-it will be a definite bonus-what Mexico realised was to keep the monies in the country,and allow the general people to prosper-thereby developing a true middle class which is the bedrock of stability in most countries.
