I have posted the same on FT, some people find the spreadsheet useful for MR since it can easily identify the cheapest hotel in your area of choice. I have created Excel spreadsheet available on Google and setup a very basic web page for it. Version 0.5d should provide useful information to users as is, but it is not tested. Features (some might only work with Excel 2007) include: The ability to get Room prices for any date range (up to 14 days) during the next year. Getting Award as well as Cash&Points availability for the same dates. Selecting hotels to be searched based on region, country or state (US only). Sorting and filtering ability based on multiple criteria. Calculating Cents/point for Awards, Cash & Points and 5th night free. Ability to add approximate taxes percentage in cents per point calculation. Ability to consider "points not earned" (SPG or AMEX) in cents per point calculation. Hotel Category identifies hotels that are not bookable, Not participating, Limited participation or SVO. Ability to identify the cheapest hotel room (before taxes) in a region, country, state, city for a given date. Automatic update of foreign exchange rates. known issues: Getting price information sometimes doesn't return full information (most common with China). The spreadsheet is setup to retry these once, user can change the number of retries to any other number. The program will report the number of hotels which failed to pull information. If SPG.com or web connection experience problems, the web query might hang. Pulling a large amount of data can take 15-30 minutes (depending on PC and connection speed). GUI interface/feedback requires work. Please report any issues, suggestions and enhancement requests and I'll do my best to fix/accommodate requests as they come in. Please note that while the spreadsheet is a .xls file (Excel 2003 format) all the development was done using Excel 2007. I might not be able to fix Excel 2003 specific issues. The next version will be Excel 2007 only.
