Wanadoo. £17, 2Gb. 0.5Mbps (1 meg if close to exchange), Dynamic IP. Not for anything other than browsing/downloading really.
Crappy modem (albeit free) relies on PC for connection info. As Adrian says, an ADSL/Firewall/VPN passthrough combo is a nice idea. (I use a Netgear DG834).
Get a fixed IP if you can. Then you can VPN in to home if you are staying in the hotel and get at your files, e-mail etc. Why do this? Hotels often have pathetic bandwidth (28kbps etc), so you get more joy VPN-ing into your home PC using RDP (Terminal Services - ask your Techy bods) and browsing from there. All you are sending to your laptop is pictures of your home PC so life becomes as fast as your home PC's broadband connection! Just don't try printing...
HTH
