It was enjoyable, but you definitely had to make your own fun sometimes. There wasn't a ton of backstage to it though, since it isn't a ride. We weren't even allowed up in the catwalks in the chambers, which used to be an on-stage role for a Cast Member when it was Alien Encounter.
It was its own rotation because it had so many roles, so that was always nice to not have to move between attractions. A lot of the positions were indoors, which was a plus. Not to mention you got to sit down during the shows and relax a little if you were on a theater role. Plus our breakroom was in the same building as the attraction, so that was convenient too.
