Rainbow Valley

This isn't your everyday level, its much much harder.  You have to build a park, but you can't adjust one piece of land, or move one tree.  All working in a valley.  Most of the time you can build paths after the rides, but this time you have to consider it heavily when you place the ride.

Overall

You can make lots of money, but if you get problems, its hard to fix.  Lost guests are a nature due to a poor path system.

Each coaster has to be above the trees, platforms are hard to find

Potential for this park, a 3, just because its so long.  Its thin and the tree situation is annoying.
