What are AP's and UMP's?

[ninap]

I am new to this board and am closing on my resale next week. I feel foolish even asking this question, but I can not figure out what AP's adn UMP's stand for. Please help

AP is the Annual Pass you can purchase for the parks. (PAP is Premium Annual Pass and include the water parks and PI.)

UMP are Unlimited Magic Pass or what used to be called Length of Stay Pass. It let's you visit the parks, waterparks and PI for the length of your stay. DVC members get 10% off the price for these passes.
