Crazy Water Park closed for at least 3 days

Remember the Crazy Water Park? Hamas did not like it and closed it:

Hamas ordered the "Crazy Water," water park in Gaza closed due to men and women mixing at parties held in the park, Israel Radio reported on Sunday.

A spokesperson for the Hamas government claimed that the park was actually closed for only three days, because it did not have a proper permit. "Men and women are mixed throughout Gaza," the spokesperson said. "The closing is just a warning."

Why do I have the feeling that the "no proper permit"-story is just BS?
