My personal humble opinion is....
There are enuff clubs on the island now.
They have to compete like hell to make a profit. It's a small island.
Not sure what the feasability would be on the mainland.....guess it would depend on the area.
Would definately do some first hand research b/4 you go any farther though.
Go check it out for yourself.....look at different areas.
Remember....Belize consists of about 8800 sq miles total....and approx. 260,000 people....give or take 10,000. About 70,000 of those people are in Belize City....the rest are spread out in other small cities and villages......some of which are very remote. You will probably find that a lot of people in remote areas are not interested in going to a club. Belizean income for most does not permit such luxuries.
For example....a laborer in Belize gets paid about $45 bz a day....that's $22.50 US.
Hope this helps
