What are black out periods in a theme park?|197883

In my last question I asked about the Universal Studios Season Pass and what it has to offer. In an answer someone referred to a black out period when explaining the signifigance of a season/_Power Pass_. If someone could explain a black out period that would be amazing!

Black out periods are times when you cannot use your pass to gain admission to the parks. For example, an annual pass is good all year, 365 days per year. The theme parks usually will _black out_ seasonal passes at times like Spring Break, Summer, and Christmas/New Years.

Here is a link to a calendar with the dates for 2009 when you cannot use a power pass.

A blackout period is a chunk of days (often holidays and other times when the attractions will be in high demand) where free/discount passes are not honoured.

those are days when the park is closed to the general public.
