The internet access has been there for only two years. It was still there this October. There are no in cabin connections. The internet locations are next to the Guest Relations desk in the Grand Foyer (Plaza Deck - 5th deck) and outside the theatre and library (Promenade Deck -6th deck). I thought they were slow and expensive when I used them after they were first installed. I didn't use on the last trip, nor did I see too many people using them.
