"...you get to be relieved of your responsibilities for the day and go do something fun" is a terrible attitude to take about the underlying work if you're trying to make games. If you didn't enjoy making it, they won't enjoy playing it.
Edit for the downvote: I have a small games studio. I also attended d.school and have an EMBA. Large companies will have some people who phone it in day-to-day. A small studio needs people to be committed and giving 100% basically at all times. If you've done your job properly, you might find that you have to force people to take time off or even go home at the end of the day. That's what I was getting at. Field trips might form part of that engagement strategy, but not as a respite from an otherwise grim day-to-day.
