Fast Cash... a lot of Cash
To get a large amount of money, find a piece of scenery in your menu that can go on the ground such as the Wood Block in the Mine Themed Scenery. Next, make sure you have a nice sized Thrill Ride (Enterprise works the best) to place on the blocks. Select the blocks to build, then place a 4x4 section of blocks (with Enterprise; the size will vary depending on the size of the ride) and hold the Shift button to raise the height of the stack. Add on about 20 blocks to each of the 16 already on the ground. Next, build the Enterprise (or your Thrill Ride) where the blocks are. The cost of construction of the ride should be a large negative number. This is the amount of money you will get. After the ride is built, demolish it to get more money.

Multiple names:
You can have more than one person with the same name (which works well when using the cheats) by changing the capitalization of various letters. For example Chris Sawyer can be used on another person by making all letters lower or upper case (chris sawyer and CHRIS SAWYER).
Guests never leave:
Put a "No Entry" sign by the entrance, facing away from the entrance. Guests can still come in, but will not leave. Note: This may cause your park rating to decrease, because many guests will be "lost" and want to go home.
Extra building space:
Build a ride or attraction such as a maze. You can now build on top of that with smaller rides (for example, bumper cars).
