Have you talked to the front desk to find out how to contact the router? Most of the places I have used require a user and password given to you by the front desk. They give it out to registered guests.
They run DHCP, almost exclusively, so you should start by opening a terminal, run 'ifconfig wlan0' and see if you have an IP address. 'iwconfig' will show the wireless options. 'iwlist scan' should list the wireless access points your system is seeing.
BTW, wlan0 is the name of your wireless interface. Yours may differ, 'ifconfig' by itself will list all interfaces, from that you can find out what your wireless interface is named. ( all commands without the quotes...)
One last thought. If you have added ANY program that deals with either wired or wireless interfaces, it may have screwed up the Wireless Manager applet that is standard on all buntu installs. I added WICD, then neither worked. The fix was to use only one. So, either pic the wireless applet, or WICD,not both.
