If you put a sign saying no entry, on the other side of the entry no people can get out but people can enter the park.
Raise the prices of all the rides in your park to their excitement rating. For example if the excitement rating is 8.27 you should charge them $8.30. (Round up) Guests will never think you ride is too expensive. NOTE: This trick wont work for certain rides such as cinemas or dodgems so you should either demolish them or lower the cost 10-50 cents. Make sure that all your rides have been re-priced this way or guests will only go on that ride.
You can have more than one person with the same name by changing the capitalization of the name's letters. Example: There can be four Chris Sawyers in your park if one is named Chris Sawyer and the others chris sawyer, CHRIS SAWYER, and cHrIs SaWyEr.
To raise your scenery just press the SHIFT key and you should be able to drag your scenery up or down.
Enter John Mace as a patron's name and he will pay double for everyhing.
