Lambada and Bob K, thank you for the information and photo link.
The park looks great, much the same as mamy water theme parks in the US. Opening day looked like a huge success.
I was wondering if many tourists have found it yet. Although it was just opening day, I didn't see many gringos in the pictures. It seems like something that families with kids would enjoy, a nice refreshing day in the water at a very reasonable price, I think.
