If you are a Marriott fan, there is a new site available now called the Marriott Rewards Insider

For tips about specific Marriott hotels, and nearby activities, this could be a good place to look. Typically I prefer to use tripadvisor for things to do if I have time to look around a city, but I can see how this might have good info when you are making a short stop somewhere and just have time to find what what is close to the hotel.  Check it out.
