I can see what the idea is, but promoting Belize this way can go two directions, and I fear for the worst:

The tourism we have suffers from cruise ships, as does our fragile nature. Belize is just not made for mass tourism, and what do we need it for?; we don't have that many mouths to feed; in Belize the profit will rather be for the favoured few.

This can lead to an anti promotion, along with, as Lan says, small criminality in Belize City. The Cruise ship cattle is already briefed on sea about the dangers in Belize City. Ask any Cruise ship tourist what their impression about Belize was, and it will be: "Very dangerous place".

This is not the image we want to spread, also keeping in mind that it is a false image!

Conclusion: Definitely bad news.

Live and let live
