Las Vegas hosts a ton of trade shows every year. The next time you travel to Las Vegas, have I found a deal for you!
A lot of the strip hotels have spotty wireless internet (they want you in the casino not surfing the web) and those that do have internet charge heftily for it.
The convention center has good WiFi, but again they charge for the privilege.
Add the two together and your internet bill will be larger than your food bill.
While at the Consumer Electronics Show I found a better solution that is somewhat unique to Las Vegas.
