Look, it's 2010. Why do hotels still often demand that you PAY for wifi in your room? Instead, they should advertise it as a free service, which would positively make people WANT to come there. OK, maybe put a gigabytage cap on it or something, but come ON, people - get into the info age.
Hat tip to Martin on http://scienceblogs.com/aardvarchaeology - he agrees with me. As do all Right Thinking People. Next time you're in a hotel, leave a comment to the above effect in the guest comments.
