I went in January, where it was very possible to do two parks in one day. But, it was just me and my BF (both in early 20's) so we were able to go at a faster pace than if we had children. On Sunday, we did AK in the morning, and BB in the afternoon. Another day, we did AK again in the noring, and I think MGM in the afternoon, and then MK for fireworks (our last day). Good Luck with your decision, but just remember to have fun!
