I don't know the exact info that was on the channel...
but on the stateroom tv... there was a channel that showed a map of where you had traveled... distances, knotts, wind speed, air temp, and I think water temp as well... it was really neat turning it on and seeing where you had gone! I bet he or she could get a lot of info from that!
Also, there is a shopping guru on the cruise who has posted hours in the navigator, I am sure they could get you currency exchange rates, as well as guest relations!
