I agree! 20 years ago Cozumel was a sleepy Mexican town where we would go for a week to enjoy the local culture and food. People were great, food was good, and the diving was awesome.
Now, it's become nothing more than a cruise port catering to the thousands of American tourists who visit it for several hours every day and then leave. It's lost all its Mexican mystic and wonderment.
Unfortunately, I see this coming true for alot of ports and is an unfortunate byproduct from the success of cruising. Grand Cayman is just another domino in the game.
