Yes, in Planet Coaster 2, you can build water parks in addition to theme parks. The game allows you to construct various water attractions such as wave pools, lazy rivers, and custom-built waterslides. You can also add essential facilities like changing rooms, sunbeds, and lifeguards to enhance the guest experience.

The shared park feature in Planet Coaster 2 allows players to create theme parks together, but it has some limitations. Only one person can access and build in the shared park at a time, and others must wait for their turn. Players need to save their progress to let others see and build upon the changes made. This limitation prevents simultaneous building and may affect the collaborative experience.
