For anyone going here's my advice...pay for the early admission! Does a couple things, guarantees a Clam bucket for the most part, allows you to shop without the crowds. Last year on Saturday I paid the early bird price, got in, got my bucket, filled it up with all my stuff and was completely done before the big crowd was even allowed in. Had the rest of the day to have fun with my wife! Saw all the people I needed to see, actually had time and space to talk to them and met some new friends too.
Worth it 100% if you have an organized list of what you are there for!
