Disneyland WOC with ECV?

Can anyone tell me about seeing WOC with one person in an ECV but the rest of the party not? Either by doing a dining package or just getting a spot without a package?

How is the person in the ECV able to see since everyone is standing for WOC? And is the rest of the party able to be in the same area if there's a designated ECV section?

I'm familiar with how it works for Fantasmic, but that's a little different because everyone sits for Fantasmic.
