Title says it all, mostly.

I've managed to get the 2000 prestige, I have lots of tanks filled with various species, decor. Everything seems to go well, apart from a couple of tight spots here and there. Visitors needs are met also. I have podium and lectures for my biggest tanks. But for some reason, I can't get over 50~ guests. Tried adding a few pathway arrow to push visitor to more remote area, didn't seems to help.

What am I missing ?

Thanks, that worked. Added a couple more podiums, and set every podium I had to the highest frequency, got the guests in no time.

Beware you can get negative points for too much frequency if you don't change th talk topic. Keep an eye on that; I just ran into that on that same level. I've had the people, but can't break 1800 points yet.
