Yes, there are lots of abbreviations used here, and even when you've been doing this for a while, you often have to stop and think about what the poster is trying to say....additionally, there are some abbreviations that people do incorrectly - Like CS and QS (Disney has called fast-food type eateries as both "quick service" and "counter service") and there are some that are double, or nearly doubles like Space Mountain, Mission:Space, SpectroMagic, and Splash Mountain - SM or M:S). After a while though, you get used tothe most common ones, and it sure makes typing easier to use them!
