Man, it seems like every hotel in the US seems to be too cheap to upgrade their routers beyond the "b" standard to supporting "g" or even the "n" specification.
I recently stayed at a Microtel in Tampa which as usual had "b" and amazingly had a T1 line! This is a very small hotel with even fewer guests using the Internet. I gave the hotel manager who was quite interested a mini-speech on the advantage of upgrading to at least "g" and preferably "n". Come on, at least for small hotels, routers are cheap!
The nice thing at the Microtel was that you had wireless in your room, which unfortunately doesn't seem to work well in other hotels.
Currently I am in Chicago and while my hotel offers free wireless internet in the lobby, it is $10 a night in the room and to top it off it's wired in the room, not wireless. No biggie, as I always carry a network wire just for those odd occasions, but I can see if you weren't traveling alone where there could be an issue, as there is only the single Internet port in the room. Maybe people traveling as a couple might be wise to pack along a router just in case.
I sure wish more hotels would upgrade to at least "g" if not "n"!
