RCT 1 Problem.

I just started playing this game after many years that I forgot about it. I started playing Funtopia, and I've been really successful. There's not a lot of land, and I have most of it filled with rides, and I have LOADS of money left over. Like over 80,000 left over. People are complaining that it's too crowded, and when I put more paths people get lost. How can I fix this problem?

I'm also in April of my 3rd year, and I have about 1,100 people in my park, with a red arrow by it, and I need 1,400 by the end of October of that year. How can I increase population?

Thanks,
Chaseroonie
