A cm was handing out resume? Now that is just weird, if she is not fired she will be soon.
I am sure that they would have most likely have her moved to another attraction or would have given those cm another alternative
It was supposed to be a joke. Yes, the CMs who normally work Nemo are trained to work other attractions too, so they all have other locations they can go to while Nemo is closed (source: I have worked in Tomorrowland attractions and have quite a few friends who work Nemo). They probably had her stationed there just for today (and it's possible someone will be there over the next few days) to inform guests that it's closed and to answer questions. I'm sure eventually they won't staff anyone there, especially if more construction walls are coming (to surround the lagoon).
Disneyland put up these billboards to replace the Cars Land Christmas ones that they had up for the holidays. These billboards look like they are going with the new campaign that Disney is promoting now for everyone to show their Disney Side and spend more time at the parks.
