we stopped by MGM purposely to see the lion habitat. there wasn't a line but there were a lot of people surrounding the case to take pictures of them. there were 2 young lions eating/jabbing at the bone. i was told they swtich out the lions every day or so just so that the lions can rest. i saw the two lions without a mane.. so i didnt feel like it was the real thing. however there are 2 baby cubs that are separated. they are both separated which reminded me of simba and nala! super cute!! and such a great stop to visit on the strip for free! i believe you can pay extra to hold them for a photo op!
