I am taking a cruise next week on a Celebrity ship. They claim to have internet access from the staterooms, but from what I can deduce it appears that it is some sort of dial-up system that requires Windows to use. This seems odd to me, but I'm wondering if my Mac Book Pro will work in this environment. I haven't tried to use a dial-up conncection for some years now. Does anyone know if there is any sort of internal modem on my computer that would make this connection possible?
