are too crowded? We want to buy tickets online but we have heard that they oversell or get too crowded some days and won't let more people in. We are going after New Years, Jan 2-3. We also think we are going to get the park hopper pass which means you can go from park to park in one day. What happens if you get into one and the other is too crowded? Do they let you in? An answer to any of my questions would help, if you can answer all that is great!! The sooner you can answer the better for we need to book the trip very soon! Thanks in advance.
