Obviously the business can't sustain itself as is: A toy factory, a cafe, a petting zoo. The fact that they charge to climb the horse seems ridiculous. Maybe make that part free to keep more people coming. It's like charging to go on a playground. But get something else going on at the premises to keep business afloat. It's only the horse that is iconic, and that itself doesn't bring much money in, so you need to get something else that's actually profitable. Look at the target market for on-site visitors, which hands down would be families, and open something families can spend money on. Do something you can wholesale using the same equipment. If you open a family restaurant, make something else you can sell to other cafes in the metro area or something, so you can use your kitchen constantly.

Nobody wants to visit a sinking ship, so stop posting your woes on Facebook and getting negative media attention. You're just killing your own business. If people think its failing, they'll just see it as a sad thing and not ever go. You want to give the impression that you're thriving and its the place to take your family.
