This will generate a significant loss of income for all the industries at the marina.
Assuming the blog owners:
A) Are local (they drove to harbor)
B) Don't understand the overwhelming majority of divers arrive to Fonatur by taxi
C) Or get picked up at a pier to the south (or downtown)
Not to mention Fonatur roads are fully paved with plenty of parking on the streets.
To state this will cause a "significant loss of income" is comical. Unless we are assuming people will stop diving because they refuse to walk an extra 25-50 yards from parking?
