Can't reach required guestcount on Safari Mission

[ZooKeeperLJ]

I'm doing the Safari park mission, have all completed all the objectives except reach 2800 guests.

Everything but guest happiness is 5 stars.Guest happiness is 4 stars.
I have three marketing campaigns going; the late night show, family show and one of $2500 ones.

But my guest count hasn't gone above 2750, I've been sat there waiting for it to get to 2800 for ten ingame years now and it never goes above that.

Anybody have any advice on how to get those final 50 guests?

Have you tried dropping the gate admissions price?

 

[Monsarona]

Have you gotten any new animals lately? Maybe adding a new high interest animal could push you over the edge?

 

[ZooKeeperLJ]

Yes to both. I dropped the price right down to 0 for a couple of months and have been picking up new high score animals as other animals die of old age.

I had a hard time in that mission too, but after adding almost EVERY animal,pushing informations etc etc and after some time i got over the 2800, also had built several vivariums...
