I haven't seen any evidence of hysterical laughter here. Amusement, certainly. I see nothing wrong in finding amusement in some of the situations that have been described here. Obviously a sense of humour is as variable and different amongst Disers as it is in the general population.
I remember a post from several years ago (and I doff my bonnet to the original poster, whose name now escapes me). He described being outside the general store, near the bus stop at POR. He sees a middle aged man suddenly run to the door of the store, yank open the door, and yell inside "Martha, come quick, you gotta hear this!" Intrigued, the poster unashamedly continues to eavesdrop. The man's wife, accompanied by several teenagers comes out of the door. "Martha, you ain't gonna believe this! This is only the hotel! This place is so big you gotta take a bus to get to the park. And the bus driver fella just told me they got 3 more parks too!!"
Now if that's not a lack of planning and research, I don't know what is.
