I think that any time you are willing to get at the parks at opening, and then leave by 11:30 - 12;00 for break etc, you will be alright. we have used this plan in the summer months with great success. We have however in the very crowded times (like when you are going) not been as successful enjoying returning in the late afternoon. It just always seems mobbed and packed, and worht skipping in my families vacation. Good luck!
