I am travelling with a group of 13, aged 4 to 64. We arrive at the Beach club on a wednesday afternoon and can make it over to MGM around 3pm. Is it worth going just for the afternoon, especially with an early closing time (prob about 7:30 in early December)? We will not be staying for Fantasmic since it would scare the little ones too much. In fact, many of the attractions at MGM seem less than kid-friendly, which is why I was thinking we could see just a couple of the shows and make it out. Any suggestions?
