Don't worry about your English. You are close enough to understand what you mean, and that is fine.
The only way that you will know if Belize is for you is to go there and see for yourself. 99% of the people may love it, but you may be the 1% who does not. You will never know until you are THERE. Reading about it is not the same. I think that Ambergris Caye would be the ideal place to write, but that is just my opinion.
Take the leap. Go see for yourself!
