Now that the Parade of Dreams might be going the way of yesterland, (although conflicting info exists on that fact), it might be a good time to point out something - Disney's entertainment CMs work incredibly hard. Many of them are young and are looking for that first toehold into the entertainment industry, and are attracted to the Disney magic that can't be replicated elsewhere, and a job that's fun and allows them to express their love for dance and acting.
It's no secret that these CMs are not well paid, and are often required to work extra days, and extra shifts, due to changes in personnel and the needs of management, often money that barely covers expenses, and as you can see in the pictures below, many carry multiple roles. It's not unheard of for a CM to run from the Aladdin show to the Parade of Dreams show, sometimes the Block Party Bash, and then be expected to do another Parade of Dreams, or the Electrical Parade, or Fantasmic, or any combination of the above, into the late evening. But because of their direct involvement with guests, they are directly responsible for many people's enjoyment of their day at Disneyland.
Make sure to clap and show your appreciation during performances, and let the survey takers at the entrance and exits know if you enjoyed this part of your day.
