There is an observation platform on the 4th floor at the CR to watch the fireworks at the MK. It wasn't crowded the last time we were there in October, but be there a little early in case it is. Plan B would be go to the beach area or into the CR parking area just in front of the north wing to see the fireworks. The nice thing aobut the 4th floor observation deck is that CM's is on the 4th floor also.
