2. Stray from the Plan
Although a plan is a definite must-have, you must also ensure the plan is loose enough to be strayed from.
For instance, if you have a plan to ride Tower of Terror, but you run into a fun character on the way, try to be flexible enough to stop and enjoy the character before continuing with your plan. So many magical Disney moments are hidden in those unplanned experiences, so be sure to enjoy them as they crop up!
