You may or may not be right, time will tell. I'm not talking about this year, but in the future.
The location, of course, works in Carnival's favor. Many times the ships tie up at a pier in a town/city, or tender passengers to a dock on shore. No question that makes it easier for independents of all types to compete with the cruise lines. I haven't seen the cruise port in Maimon, but it is my understanding it is more isolated than many, thus making it easier for Carnival to exercise control.
But as I said, time will tell. I'm not ready to agree that your post is etched in stone.
Many on DR1 will remember Dean and Wanda Brown, Dean was the top seller for Perdomo Real Estate before the bottom dropped out of the market. When that happened they went back to North Carolina to work.
They go on a lot of cruises and are booked on one in December, I think, that leaves from South Carolina and has Maimon as one of the stops. I'll be very interested in getting their thoughts regarding Maimon and what they hear from other passengers.
