$20 a head, for, um, maybe 60 minutes?  felt way overpriced, even though $20 in vegas is NOTHING.  dolphins were cool -- but I don't normally support \"zoos\" (my PETA tendencies)....maybe 10 of them?  leopards were all asleep and far away.  one white tiger was pacing back and forth along the fence line...seemed caged in (duh).  this wasn't a \"sad\" zoo, but pretty much lacking in diversity.   long and slow line to pay...even though 12 people in front of us.  why so slow?  they try and sell you other shows/packages at MGM properties.  so you have people going, \"ummm...maybe that one...\" and so on.  very SLOW process indeed.  would I go back?  no.  unless i really LOVED dolphins, which I don't.
