Remember that you don't need to build just coasters to complete this objective; flat rides like the Swinging Ship and the Merry-Go-Round also contribute to ride profits, so keep some of these scattered around. Some thrill rides can net about $3,000 an hour and even the Observation Tower can net some $2,000 an hour. As long as you have a variety of well built rides that attract a lot of guests, you should have no problem with this objective. Previous experience with Vertigo Views and Wacky Warren WILL HELP. Remember to keep the guests happy at all times. There is no time limit to this scenario, so take as long as you want (an editor of this took 9 years to do it).
