Last Dec. (about the 27th) I waited for about 20 minutes in a line to get into the parking lot to Animal Kingdom. I was stuck right around the big McDonalds by the value resorts. So I turned around and went to MGM which was almost as bad a mistake. I actually got one of the last parking spaces, went into the park, saw it was a nightmare (no fastpasses left, R&R was about 120 min wait, etc.) so I left and went shopping with the family. I later found out that those days AK reached capacity about 3 times in a week and either 3 or all parks reached capacity that day. I had NEVER seen the parks like that before and haven´t seen it since (was there last week and it wasn´t even close to that).
