Costs of entering countries, fees, taxes, hidden charges of caribbean cruising.

[manawatuman]

Hi, we're planning on cruising the Caribbean and central American countries next year.
Having only ever done local coastal sailing, i was wondering what to expect from different countries and ports when it comes to fees of entry.
I heard some charge $300 to enter, is that correct?
Are my dreams of free living about to come to a rude awakening?
Thats Half the reason I wanted to get away from land taxes, tolls and parking meters. To be free and self sufficient. .....
