Gravity Gardens

Overview
Gravity Gardens is a huge park with lots of trees. The local authority didn't like park rides other than roller coasters, so you have to put up with that. Lucky for you, stalls and shops aren't forbidden or you would have a problem facing dehydrated hungry disgruntled guests.

Scenario Guide
Because you have more than enough space, don't go buying more land than you need. Not only will it be pointless (well almost), it will also cost you $100 per tile. So you are probably better off using the land you own.

Because the only rides you have are roller coasters, this park will not be very popular for those guests with low nausea thresholds, so be sure to build nice, gentle roller coasters as well as epic, fast roller coasters.

Due to the objective of this scenario, achieving park value of 500,000$ with only coasters is pretty easy, every year one coaster should be built, try that the small coasters will be use for the little kids as the gentle rides and the suspended with high intensity for the adults.

Though it's easy to get the park value objective, repaying the loan can be annoying if you take a big loan on the start of this scenario, so you will have to charge your guests 50$ to enter the park, and make them buy drinks and food for over 3$, of you won't do it, your park value will just keep dropping in the time being. Doing campaigns of 50$ to attract more guests without spending a bunch of money and will help you get money easily.

This scenario is pretty hard, the objective itself seems easy at first but as you progress, you will find out that it's more difficult than you thought. the no time limit is very useful, as this scenario can take more than 6 year games.

Another different approach is to try not to spend more than $15,000 in any Roller Coaster you built. Add No-Entry signs to areas without any rides and once your cash is low and guest count is at least 1,000, close all rides and the park, and remove guests from the park using no-entry signs. After only 100 guests remain, remove those signs, re-open the park and charge over $50.00 for park entry (make sure your park is developed enough). Advertise with free food vouchers and advertising campaigns once you get the money. If you can muster 1,500 guests, you would have recieved $70,000 from just 1,400 guests. Pay off all your debt first then build some more, continue advertising, close the park once guests stop flowing, repeat procedure until you get a $500,000 park value. Try not to take out loans if your debt is $20,000 or more because you'll need to pay your loan back too to accomplish this park's objective. Your park value would fall when you close the park, but it'll recover fast once re-opened.
