Can't score 300 tourists (Tropico 6)

Mission Tropeland, the complexity of the standard.

Seems that any change puts tourists at first, but then their number is again on the decline.

Tourist rating of 90+
Pollutant: no
The satisfaction of the people 98% and sometimes 100%
Relations with the powers to keep difficult, but in the whole 100 but one or two runs from 30 to 90. But even when 100 tourists on the strength of 150.
Tourist buildings a lot.
Maximum capacity of ~500.
Beauty 100.
Freedom and the crime situation - it's hard, but overall green.

More money million. Tourist port enough, there is the airplane one. What do these bastards want?
