The good news is that the hotel has free wireless (albeit you do have to go down to the front desk and request a new access code every 6 hours). The bad news is that on the second floor, with my PowerBook G4, it is very flaky. Sometimes no connection, sometimes no DHCP, sometimes works great all evening.
I am currently camped out in a third floor hallway as it is in the "no DHCP" mode.
Front desk unfortunately doesn't seem to be able to do anything, like reboot the nodes - they just tell me to use the Windows computer that's wired up in the tiny business closet.
The wireless is from The Cloud Networks.
