Looks like an abandoned park. The new Ventura reservation system didn‘t work properly and you can just do it online -> what about foreign visitors without internet? On the information board on-site was stated, that just online payments are allowed. But the necessary registration code was missing -> hence the sites are just bookable online with an additional reservation fee of $10 even if already on site without a reservation -> in my point if view this is not acceptable.

The online booking took me 5 retries. The website just stepped back without any error (in the end I found that they rejected my email address!, but no error at all)
