another thought - if you don't get the USB plug set up -
if you have a built in modem - you could use the free dial up on the link that was posted in another thread here.
then you just need a spare phone line to connect to the hotel phone line.

I can hardly believe they are giving away free unlimited dial up - but here's the link

Toll Free Number

Unlike other service that just give you a limited number of hours per month, Great Dial Up is unlimited! We even use a Toll Free Number so there is absolutely no cost to you! You no longer need to wade through huge lists of local access numbers. Everyone uses the same Toll Free number to dial in. It has never been more simple.
