Stamford Hotels in Australia have started to use viralmarketing by creating cameo videos that peole will pass around. My wife sent me this link. There are a couple of different videos on the website. they are fun and fall into the category of infectious from a viral standpoint.
Here is the link to the page with two clips.

Let me know if there are any other examples of hotels seeking to differentiate themselves.
