Hi.. whoever.. too late to work out who's the thread starter..
Couldn't you just plug it in the phone socket, and use the M$ Connection Wizard, to let the machine find a local ISP? I'm not aufait with the US call billing system, but in the UK, it would be a nice local call charge ISP!
He can always delete the [now default] connection once he leaves the hotel.
A few pence worth of my thoughts..
Cheers
