Rename the guest with the following names:

John D Rockefeller-Increase your money by $10,000
Chris Sawyer-Cheer (Lp) - All guests applaud you & Jump into the air
Mouse-All guests stand around looking down at the ground (are they looking for mice between their feet?)
Guido Fawkes-Enables the "Advanced firework editor". Usage: Scenery -> Firework Mixmaster -> Fireworks Displays -> Add firework display -> Advanced firework editor
Atari-Cheer (Fade) - All guests applaud you
James Hunt-Moss (You are given a buggy vehicle to ride in)
D Lean-Open the "Flying Camera" routes editor
ATITech-Every Person (both guests & staff) move super fast, though the game time passes at normal speed (rides & coasters do not speed up) (Expires after 20 seconds)
Make Me Sick-All guests become Sick and vomit immediately
Jonny Watts-PeepCam (see the world through the eyes of the guest who you just renamed)
John Wardley-Coaster Heights (ride & coaster tracks can be built without height limitations)
Frontier-Unbreakable (Buildings/Rides/Coasters do not break down any longer)
Jon Roach-Ride All Rides (make all guests ride every park ride before leaving the park) OR, it may just make guests ignore their nausea rating
Sam Denney-Ride All Coasters (make all guests ride every park coaster before leaving the park) OR, it may just make guests ignore their nausea rating
Atomic-Big Explosion

Here are good cheats that ive taken from different sites! The last couple where you have to rewrite the program might not work, i dont think it worked on mine, but you can try it if you want! Good luck, and I LOVE RTC3!!!!

The cheats with a (1) after it require the update 1 patch for the game.
You can get the updates for RCT3 by inserting the RCT3 cd and when the autorun pops up, look for the button that says "updates"! Click it and it will automatically look for updates!

Guests will ride anything:
Note: This procedure involves editing a game file; create a backup copy of the file before proceeding.
Use a text editor to edit the "options.txt" file in the "c:\documents and settings\\application data\atari\rct3 " folder. Note: this folder is "hidden" by default, so you will have to enable Windows to view hidden files and folders. Add the following lines to that file. Note: You may have to restart a scenario for the changes to take effect.
GuestsHaveFixedHealth 1
GuestsIgnoreRideIntensity 1
GuestsIgnoreRideNausea 1
GuestsIgnoreRideCost 1
GuestsRevisitRides 1
GuestsRideUnratedRides 1
Your guests will ride anything (uber-extreme nausea, intensity) with no problem and keep coming back for more.
