WDW Value Resort Prices

I was inspired by my wife's recent post to make a graph to look for patterns of when to visit Walt Disney World.
Here is a graph of the cost of a standard room at the Walt Disney World value resorts (Jones favorites) in 2011. The data come from this site.
I've color-coded the months to help identify the dates. It looks like the rates are least expensive on most weekdays in January through mid-February. You'll pay the most for a room (about twice as much) in late December.
