Is HHN similar to MVMCP where people buy tickets just for the night and can't come in until a certain time? Will the park be mobbed in the morning? My DH & son might go up to Legoland Oct. 29 or 30. I thought that would be a good time for me to finally take my girls to US/IOA, but I don't want our first trip to be a mad house. We live close enough that we could plan it another weekend, I just figured it would be convenient for us all to go up together. Thanks!
