Not that I've seen. But, I'm not sure how useful it would be anyway. Depending on the dates of a stay, the check-in date and the number of nights, I've found that rates on any given night can fluctuate, and different promo codes can come into and out of play. I probably wouldn't rely on such a calendar if it existed, and would still run specific searches anyway, to be sure I'm getting the best rate. I normally use a spreadsheet with variables for my dates, number of nights, promo codes and property code, and then run a macro to initiate a web search to return the applicable rates. It makes it a bit faster to run recurring searches or searches with changing variables, but it still comes down to several individual searches.
