One of the great things about Disneyland... and what truly sets it apart from other parks... is the density of detail. Practically everywhere you turn, you'll find a little "extra" something to make your experience even more magical. Often, these are very simple things; neither elaborate nor particularly costly. But... times change and things come and go.
There was a time when they offered "Mint Juleps" on the Mark Twain. Often, a dixieland band would provide music in the evenings. Today, gliding around the Rivers Of America after dark is a relaxing and soothing experience. The festive party atmosphere of yesterday was a lot of fun, though!
What "little thing" about Disneyland has gone missing that you'd like to see again?
