What kind of park
The first thing you need to decide is to figure out what kind of amusement park you want to build. This is crucial, since it will decide the outcome of your whole project and will give direction to your park.
Not having a basic idea and foundation on which follow up could end up resulting in the park not being built up to standards, so you want to go on and decide what you have to do as early as you possibly can.
The next thing you want to do is to find a massive chunk of land on which to build your park. Make sure that the land that you have selected can be accessed easily, and is big enough to hold and do everything you want your park to do.
Not selecting the right location to build your park could end up resulting in it being a failure, before it even goes on to open up.
Now you want to go on and get legal permits that authorize you to build an amusement park on the land that you have selected. You don’t want to go in and build the park, only to later find out that you didn’t have permission to do so and that you might have to take it all apart.
Now you want to hire professionals to see through the whole construction process and some to even help you design and follow up on the project.
These professionals will be crucial to your park doing good and it would be a little foolish to do the whole project alone, without any expert help at all.
