Yeah unfortunately I don't see an option for that. I clicked on the wifi icon in the bottom right corner (icon tray) and the only options it allows are connect/disconnect based on whatever your status is.

I opened up the Network & Sharing Center and there's no where to Forget Network either. I even disabled and enabled my wireless adapter and tried releasing/renewing my IP through the command prompt.

No dice. Guessing I'll have to wait for the hotel's router to boot me like it does every 24 hrs.
