Which Lights at MGM. You have Fantasmic, which is a Lazer Light, character show. You need a park ticket to get to see the show at MGM. The other lights may be the Christmas Osborn Lights, in which you also need a park ticket. You can rent a boat near the Boardwalk and they will take you near the Fantasmic show, but I don't know how much that is.
I am going to move you over to Theme Park Strategies. I am sure you will receive more replies to your question.
