Having faced the same problem I found that using hotel phones cost an arm and a leg. Although a lot slower it was actually cheaper to use my mobile connected to the laptop to send and receive emails. Surfing wasn't really an option at the sort of speeds available over the normal mobile network although that should not be a problem with the latest systems.

Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
