I've borrowed the Go-Pro camera from the concierge before. It was a while back but It's the full setup -- had chest mount and everything. Took it scuba diving and got some amazing shots of turtles.

I don't get the language around the disk and having to return it nightly -- they had the same language when I borrowed mine, but they let me check it out the day before and keep it overnight since I was leaving on a pretty early scuba trip.

The concierge team is pretty flexible -- I imagine they just don't want you running off with it for a week at a time.
