Reminds me of an earlier thread, where we said some of us wouldn't mind a hands-on with those life vests during the flight, rather than just the fashion show.
Same thread, IIRC where somebody else suggested there should be an escape slide mock-up to practice on in the departure hall, rather than only the shopping mall.
Maybe there also should be a way to activate the floor-path lighting during the safety briefing.... not everyone could see it maybe, but it would help.
