staying at poly cant wait.
we are avoiding early entry because I have a hard time getting kids to leave one park to go to another, but we will be at each park at opening.
Use the ee combined with fast pass whenever you can. Then do lunch and head back to your hotel or head to a non ee park as it starts to get crowded. I really believe this is the best strategy.
