If you are paying $200 per person for a 2 tank dive out of Belize City, then the cruise line is getting $100. I have spent some time in Alaska and have a friend who owns a business in Juneau. What happens is that the Cruise companies squeeze and squeeze while making their own outrageous cut off the tours. Gradually, the operators go out of business because the land based tourists stop coming and they cannot make money after the cruise companies take their cut. The next phase which began years ago in Alaska is that the lines buy the local operators and full control pricing ect. Then NO locally owned business survives.
Here is the math on Belize City scuba trips. Regular rate is $123.50 for a 2 tank dive. It is expensive because gas is expensive and it is a long way to the reef from Belize City. You can be sure that NCL and the others are paying at most $100 for the same trip. Then they are marking it up to their passengers to $200. They make $100 for selling the trip. The operator probably nets about $40 at the rack rate. at $100 they net $16. That's fine and dandy as long as the cruise ships keep coming and they do not decide to squeeze them further. What has happened in Alaska is that they have squeezed them more. Why? Because they can. They have HUGE leverage. The cruise industry has literally killed whole towns in Alaska. The local economy becomes so cruise centric that there is nothing else. The town of Skagway sees up to 12,000 passengers A DAY! The year round population is 800. On a nice Friday night in the summer at 8pm it is hard to find anything open. WE could not even find an icecream cone. Most of the stores are actually owned by the cruise lines. Princess Diamonds ect... What land based tourist would visit a place where everything is closed in the evening? I visited in an RV.
2 weeks ago, I was in Philipsburg ST Maarten. The first day there were no ships. Half the town was shuttered. It was like being at Downtown Disney when everything is closed. The next day 1 ship was in port. All of the stores were opened. What do you think we found? Princess Diamonds, Diamonds International, Tacky wannabe Jewlery, and a chain called Shipwreck Shops which sold souvenirs. Shipwreck Shops were on every corner selling the same stuff. Meanwhile in back alleys, locals struggled to get anyone to look into their shop. They could not compete and will be squeezed out by the chain stores selling bling and offensive tee shirts.
Those of us that love Belize love it because it is NOT Downtown Disney. If I want that, I'll go there. Most of the business owners will not be able to negotiate good contracts. I have seen what happens in other places. When I visited Placencia, it had only one paved road and that "road" was a narrow concrete sidewalk. People go there for the simple way of life. It is refreshing. It is a slippery slope when improvements start to support thousands of "Morris"es (we will see who get the reference) that want things like AC, Diamonds International, and dust free streets. There will be no going back.
