Little Rays was awesome when I went and I'd gladly go again even if NO animals change, nothing is made different and they let you hold the same animals!
It was the hands on people skills the staff had that I loved. And quite frankly, to some people, holding a tarantula, petting a caiman and holding a burmese ARE exciting. That's what I held anyways.
Also, they do the special shows too. Of course, it costs more but any establishment has a right to charge as much as is needed. If you want a thrill, why dont you pay for a special show for yourself!
