RollerCoaster Tycoon 2: Triple Thrill Pack Tips

Max Park Rating
If you are havving trouble raising or keeping up your park rating, here are 6 ways on how to do it.
1. Look at your guests thoughts. If they are saying I need to go to the washroom, build more washrooms. Same goes for drinks and food.
2. If your park is messy or the little notification box says "Guests are complaining about the disgusting state of paths in your park, build garbages and hndymen.
3. Build more mechanics if the notification box is saying... say, Medusa still hasn't been fixed.
4.Try not to make coasters crash or blow up.
5.Do not kill or torture guests. ( Drowning them or putting them in a hole till they are really mad.
6. Make Fun Land as kewlz was saying.
I hope these hints work for you as they did for me.
